1 Introduction
The United Nations Framework Convention on Climate Change defines climate change as “climate change directly or indirectly caused by human activities altering the composition of the global atmosphere and observed natural climate variability within comparable time periods,” and distinguishes between climate change caused by human activities and climate variability caused by natural factors (
Sands, 1992). The global community has increasingly recognized the considerable threat that climate change poses to human survival and development. There is now a broad consensus on the need for proactive and effective responses. Wang et al. (
2023a) reviewed the current state of global climate change and highlighted the urgent need for mitigation and adaptation strategies. Mitigation refers to actions aimed at reducing greenhouse gas (GHG) emissions or enhancing their absorption (
IPCC, 2023), while adaptation focuses on adjusting human and natural systems to minimize the damage caused by climate change and to capitalize on emerging opportunities (
IPCC, 2023). Both strategies are interdependent and essential for effectively addressing the multifaceted challenges posed by climate change (
MEE, 2023).
Since the 1960s, satellite technology has advanced rapidly, with applications in remote sensing, navigation, communication, and scientific research. Satellite remote sensing involves the use of sensors on satellites to gather data about Earth’s surface and atmosphere. Compared with other observational methods, satellite remote sensing provides frequent, repetitive, and large-scale coverage (
Yang et al., 2014). This capability has enabled the collection of global, long-term, continuous, and objective data on the atmosphere, land, and oceans, offering critical insights into climate change and supporting the validation of climate models and theories. Satellites can monitor GHG concentrations in the atmosphere and track their sources and distribution patterns (
Zhu et al., 2022, Shen et al.,
2023). They also measure critical parameters, such as vegetation cover, soil moisture, and surface temperature, to assess climate change impacts on terrestrial ecosystems (
Weiland et al., 2023, Aziz et al.,
2024). In addition, satellites monitor sea surface temperatures, glacier retreat, and sea level changes, providing valuable data on the effects of climate change on marine ecosystems (
Ahmad Affandi et al., 2024, Bij de Vaate et al.,
2024, Macdonald et al.,
2024). Remote sensing satellites launched and planned globally for addressing climate change are detailed in Appendix A.
Several reviews have already addressed satellite-based climate change research. Yang et al. (
2014) conducted a review of satellite remote sensing for climate analysis, revealing insights beyond the reach of traditional climate models, such as the spatial heterogeneity of sea level rise and the cooling effects of stratospheric aerosols. They also identified challenges related to the short duration of satellite observations and emphasized the need for enhanced long-term monitoring. Zhao et al. (
2023b) conducted a comprehensive review of the application of satellite remote sensing in monitoring and quantifying atmospheric components such as GHGs, clouds, and aerosols; oceanic components including sea surface temperature, ice melt, sea level rise, ocean currents, mesoscale eddies, phytoplankton, and marine productivity; and terrestrial components such as land use and land cover. Zheng et al. (
2023) reviewed the application of nighttime light (NTL) data in urban research, including its use in tracking urban expansion, socioeconomic patterns, environmental change, and human activity, and highlighted its potential in quantifying light pollution. Wang et al. (
2025a) reviewed the use of multisource remote sensing data for estimating terrestrial carbon fluxes from satellites, with a focus on global-scale inversion of gross primary productivity (GPP), net biome production, carbon emissions from land-use change and wildfires, and atmospheric CO
2 concentrations. Prentice et al. (
2024) presented a perspective on remote-sensing-based numerical models using satellite-borne measurements of light absorption by vegetation to estimate global patterns and trends in GPP, identified the challenge, and explored ways to improve their reliability. Liu et al. (
2024a) conducted a bibliometric analysis and review of land-use carbon emission or sink research over 1991–2023, showing that satellite remote sensing and remote-sensing indicators such as the Normalized Difference Vegetation Index (NDVI) are prominent themes for monitoring land-use change and supporting carbon-related assessments.
Existing review studies on satellite-based climate change research are relatively abundant; however, most studies concentrate on either climate change mitigation or adaptation, or focus predominantly on natural ecosystems. Review studies on satellite-based climate change research that integrate bibliometric analysis with systematic or narrative synthesis remain limited and typically emphasize ecological and biophysical processes, while paying insufficient attention to socioeconomic systems and human–environment interactions that are critical for climate-related policy formulation and decision-making. This study systematically summarizes satellite-based climate change research from the perspectives of mitigation and adaptation. It reviews satellite-based climate change research in ecosystems, including terrestrial, marine, and other natural systems, as well as socioeconomic systems, such as urban development, agriculture, and industrial sectors. By combining bibliometric analysis with a structured narrative review, this study provides insights into how satellite-based climate change mitigation and adaptation research has evolved over time, highlighting key areas of research focus and underexplored themes. It clarifies how satellite-based applications contribute to both climate change mitigation and adaptation by revealing their differentiated roles across natural and socioeconomic systems. The main contributions of this study include the following:
(1) A bibliometric analysis revealing the development trends and main issues of satellite-based climate change research is conducted.
(2) A review of satellite-based climate change research is conducted, including the identification of GHG sources and sinks and emission estimation in ecological and socioeconomic systems and the monitoring of key indicators such as precipitation variability, extreme weather, glacier retreat, and sea-level rise.
(3) The research gaps in satellite-based climate change research are summarized. Extant research from the perspective of mitigation lacks the monitoring of carbon flux dynamics, tracking of ecosystem resilience, and capturing of biodiversity and ecosystem services and neglects the monitoring of non-CO2 emissions from sectors such as agriculture, waste, and industrial processes. Extant research from the perspective of adaptation fails to assess resilience and adaptation strategies to climate change and lacks satellite-based climate risk assessments for infrastructure, health, and livelihoods, especially in terms of vulnerability and dynamic exposure across regions and sectors.
(4) Future research is concluded, including addressing uncertainties in transport models, meteorological fields, initial conditions, and emission inventories; expanding global ecological zones to quantify N2O and CH4 emis-sions; developing high-sensitivity algorithms to detect small-scale emission events; quantifying GHG emissions from poorly monitored sectors; evaluating the impacts of extreme climate events on ecosystem adaptive capacity; developing satellite-based indicators to monitor groundwater, river flow, forest health, coastal degradation, etc.
The structure of this study is as follows: Section 2 presents the bibliometric analysis revealing trends and main areas in satellite-based climate change research; Section 3 reviews the document on satellite-based climate change mitigation; Section 4 reviews the document on satellite-based climate change adaptation; Section 5 provides a conclusion and outlook for future research.
2 Bibliometric analysis
On the basis of data retrieved from the Web of Science Core Collection on December 31, 2025, this study conducts a bibliometric analysis of satellite-based climate change research from 1994 to 2025 using CiteSpace (
Donthu et al., 2021). Appendix B provides details on the methodology and data collection. The disciplinary and country distributions, keyword co-occurrence analysis, co-citation network of documents, documents with the strongest citation bursts, author co-citation network, and institutional collaboration network are presented in Appendix C.
The evolution of research clusters based on document co-citation clustering is conducted, which reveals the core thematic structures and developmental trajectories of satellite-based climate change research. As shown in Fig. 1, the network comprises clusters of varying sizes, reflecting heterogeneity in research activity and thematic maturity. The 10 largest clusters, each with at least nine documents, represent areas of sustained academic engagement. As shown in Table 1, all selected clusters exhibit silhouette scores above 0.86, indicating strong internal consistency and clear topical delineation. Cluster labels, generated using the log-likelihood ratio (LLR) algorithm based on the keywords of cited documents, concisely summarize each cluster’s intellectual focus. Table 2 classifies satellite-based climate change mitigation and adaptation research based on the climate change reponse strategy classification(IPCC,2023).
Clusters related to satellite-based climate change mitigation focus on GHG monitoring and emission reduction strategies. Cluster #0 focuses on global CO2 and CH4 emissions from fossil fuel combustion, particularly in the coal and oil–gas sectors, and extends to regional emission trends and climate policy evaluation in developing economies. Cluster #2 examines CH4 emissions from high-pollution industries such as steel and waste treatment, assessing the long-term effectiveness of abatement measures. Methodological advances are the core of Clusters #1 and #6: Cluster #1 integrates machine learning with satellite observations to improve spatial precision in emission estimates, while Cluster #6 highlights satellite-based monitoring of atmospheric GHG concentrations and source–sink dynamics. Cluster #7 addresses carbon fluxes and sinks in agriculture and forestry, emphasizing the impact of land-use practices.
Clusters related to satellite-based climate change adaptation focus on ecosystem responses and risk management. Cluster #3 traces the evolution of satellite applications in agriculture, from early drought warnings to global yield forecasting and resilience evaluation. Cluster #4 expands the scope of urban adaptation to encompass heat islands, air pollution, and public health risks. Cluster #5 investigates vegetation dynamics and forest health, with growing attention to ecosystem degradation and restoration strategies under climate stress. Cluster #8 focuses on cryospheric and hydrological changes, transitioning from static glacier monitoring to dynamic assessments of drought and water-related hazards. Cluster #9 centers on sea-level rise and coastal risk, progressing toward integrated shoreline management under compound climate stressors.
The clusters express two aspects of the focus: mitigation efforts prioritize emission tracking and technological innovation, and adaptation studies emphasize ecological risk and socioenvironmental resilience.
Figure 1 shows the clusters of the co-citation network, highlighting major research themes and their representative study areas.
3 Satellite-based climate change mitigation research
3.1 Satellite-based GHG source and sink estimation in ecosystems
The ecosystem acts as a source and a sink of GHGs, with fluxes influenced by natural processes and human-induced changes in land use and climate. CO
2 and CH
4 exchange across ecosystems such as forests, wetlands, grasslands, and agricultural areas, offering spatially continuous and temporally consistent data critical for understanding carbon dynamics (
Yang et al., 2022).
3.1.1 Satellite-based GHG Concentration Retrieval Using Top-down Approaches
Satellite-based GHG concentration retrieval employs top-down approaches, such as chemical transport models (CTMs), atmospheric inversion techniques, and data assimilation frameworks, which use satellite observations to infer regional and global emissions, which complement bottom-up inventories by providing spatially continuous, global-scale estimates of GHG emissions.
Several studies have applied top-down approaches to estimate carbon fluxes. Wang et al. (
2020) estimated Chinese land biosphere CO
2 fluxes by applying an ensemble Kalman Filter framework within the GEOS-Chem atmospheric transport model, assimilating a combination of newly available in situ CO
2 measurements from six Chinese stations, Siberian tower data, and satellite column observations from GOSAT and OCO-2. Schuh et al. (
2022) used a comparison of CO
2 flux inversions from the OCO-2 MIP to argue that transport differences between CTMs lead to systematic differences in estimates of the Chinese land carbon sink. Jin et al. (
2024) generated a global spatially resolved terrestrial and ocean carbon flux data set by assimilating OCO-2 XCO
2 retrievals using the GONGGA inversion system. Reyes-Muñoz et al. (

2023) used a global ensemble of regional inversions of TROPOMI satellite observations at up to 50-km resolution to quantify national CH
4 emissions from global fossil fuel exploitation. Janardanan et al. (
2024) estimated country-level CH
4 emissions and their sectoral trends by high-resolution inversion of GOSAT satellite and surface observations using the NIES-TM–FLEXPART-variational model. Qu et al. (
2024) used annual Bayesian analytical inversions of GOSAT satellite observations to attribute the global CH
4 increase to emissions from wet tropical regions.
3.1.2 Satellite-based GHG source and sink estimation using machine learning
Machine learning techniques have been used in satellite-based GHG source and sink estimation, employing algorithms such as support vector machines (SVM), random forest (RF), and deep learning models. These approaches incorporate meteorological variables, land use change, and anthropogenic activity indicators to improve the understanding of CO2 and CH4 concentrations and their spatial–temporal patterns.
Machine learning has been applied to satellite-based carbon flux estimation. He et al. (
2022) developed a LightGBM model to derive full-coverage and fine-scale midday XCO
2 across China based on OCO-2 satellite retrievals and CarbonTracker output. Zhang and Liu (
2023) developed a convolutional neural network (CNN) method to reconstruct contiguous monthly XCO
2 over China using SCIAMACHY, GOSAT, and OCO-2 satellite XCO
2 data alongside emission, vegetation, and meteorological auxiliary data sets. Baccini et al. (
2012) improved estimates of carbon dioxide emissions from tropical deforestation by producing a pan-tropical aboveground carbon density map using multi-sensor satellite data (ICESat/GLAS LiDAR, MODIS, and SRTM). Csillik et al. (
2019) combined airborne LiDAR measurements with Planet Dove satellite images in a RF regression model to map aboveground carbon stocks and emissions across Peru at 1-ha resolution. Exbrayat et al. (
2017) reconstructed annual maps of potential above-ground biomass (AGB) for the Amazon Basin, using a RF machine-learning algorithm trained on climate data and annual AGB maps derived from passive microwave observed vegetation optical depth from a series of satellites including SSM/I, AMSR-E, FY-3B MWRI, and WindSat (
Liu et al., 2015). Yan et al. (
2023b) evaluated and constructed forest AGB models for the Taiyue Mountain forest, China, using multi-source remote sensing data (including Landsat 8 optical, SAR, and DEM) and machine learning methods (RF, Gradient Boosting Decision Tree, Classification and Regression Trees, and Minimum Distance) on the Google Earth Engine (GEE) platform. Li et al. (
2024) explored the coupling relationships among multifaceted driving variables and six machine learning algorithms in AGB upscaling estimates across 18 grassland types in China, using Sentinel-1/2 satellite images and climatic-topographical-soil data. Kang et al. (
2024) developed a hybrid geospatial machine learning model combining Ordinary Least Squares and Gradient Boosted Decision Trees (GBDT) to quantify the nonlinear effects of Land Use/Land Cover Change (LULCC) on carbon dynamics, utilizing Sentinel-2 satellite imagery for LULC classification and top-down OCO-2 NCE data. Yu et al. (
2023) established the MeSAA-ML-ECS algorithm by combining the semi-mechanistic algorithm and machine learning method to retrieve seawater pCO
2 and air-sea CO
2 fluxes using MODIS/Aqua and AVHRR_OI satellite data. Li et al. (

2 model based on a RF algorithm using MODIS-Aqua satellite data along with in situ salinity to estimate sea surface pCO
2. Song et al. (
2023) developed the MeSAA-ML-SCS algorithm to retrieve sea surface pCO
2 using MODIS-Aqua satellite data.
Machine learning has been applied to satellite-based CH
4 emission detection and quantification. Radman et al. (
2023) introduced a deep learning approach based on fine-tuned EfficientNet-V2L for methane source rate quantification using Sentinel-2 satellite imagery. Duan et al. (
2023) developed a RF model to estimate diffusive CH
4 emissions from Lake Taihu using MODIS/Aqua satellite imagery. Schuit et al. (
2023) designed a two-step machine learning approach using a CNN and a support vector classifier to detect CH
4 super-emitter plumes in TROPOMI satellite data. Ai et al. (
2024) combined TROPOMI satellite-based CH
4 concentration data and a RF-based machine learning approach to simulate atmospheric CH
4 enhancements. Rouet-Leduc and Hulbert (
2024) developed a deep learning model with a vision transformer encoder to detect CH
4 emissions in Sentinel-2 multispectral satellite imagery.
Several challenges persist in satellite-based GHG concentration retrieval using top-down approaches. Limitations in transport models, meteorological inputs, and uncertainties in initial conditions and emission inventories lead to considerable deviations in atmospheric gas distribution. In regions with complex biodiversity and anthropogenic activity, disentangling natural biospheric fluxes from anthropogenic emissions remains difficult. While satellite observations capture short-term atmospheric variability, robust trend detection requires long-term, continuous data sets. Satellite-based CH4 emission estimation using machine learning has limitations because most models rely on specific conditions, limiting generalizability. Point source detection accuracy depends on uncertain variables such as wind speed and surface reflectance. Deep learning models often lack interpretability, hindering the understanding of emission dynamics and complicating integration with transport models. Current models also have difficulty characterizing long-term variability or responding to abrupt emission events. The main contributions and limitations of studies on satellite-based GHG source and sink estimation in Ecosystems are concluded in Table D1 in Appendix D.
3.2 Satellite-based GHG emission monitoring in socioeconomic systems
The socioeconomic system is a primary contributor to anthropogenic GHG emissions, encompassing sectors such as energy, agriculture, forestry, industry, and waste. Satellite-based CO2, CH4, N2O, and other GHG detection and quantification from these sectors, providing spatially explicit and temporally consistent insights that complement ground-based inventories.
3.2.1 Satellite-based emission monitoring in the energy sector
The energy sector accounts for around three-quarters of global GHG emissions (
IEA, 2025). Satellite-based CO
2, CH
4, and N
2O emission monitoring from fossil fuel combustion and fugitive sources, mainly including coal-fired power plants and oil and gas systems, employs direct plume detection and regional scale inversion methods.

4 point sources.
(2) Satellite-based emission monitoring in oil and gas systems

Satellite-based GHG emission monitoring in economic and social systems still has room for improvement. Emissions from industrial processes, product use, and the waste sector are comparatively underrepresented. The complex, nonlinear nature of multisource satellite data sets, such as atmospheric concentration variability, seasonal fluxes, shifts in ecosystem services, and spatial changes in water availability, has not been fully leveraged in emission estimation models. Furthermore, current satellite systems face challenges in accurately detecting and quantifying small-scale, spatially dispersed biomass burning events, such as agricultural residue fires, which may lead to substantial underestimation of associated GHG emissions. The main contributions and limitations of studies on satellite-based GHG emission monitoring in socioeconomic systems are concluded in Table D2 in Appendix D.

Satellite-based climate change adaptation research in ecosystems still faces several challenges. Transboundary water and ecosystem monitoring is often hindered by fragmented policy, regulatory, and jurisdictional frameworks. Many regional hydrological studies fail to account for fine-scale geographic heterogeneity and lack standardized protocols for data processing, integration, and evaluation, thus limiting robust cost–benefit analysis. In forest research, satellite-based applications have mainly focused on land cover classification and vegetation dynamics, with less attention paid to the physiologic impacts of extreme events, such as droughts. In marine research, satellite-based monitoring has largely concentrated on surface and nearshore environments, with limited coverage of deep-sea or polar regions, and minimal exploration of emerging issues such as marine microplastic pollution. The main contributions and limitations of studies satellite-based climate change adaptation research in ecosystems are concluded in Table D3 in Appendix D.
4.2 Satellite-based climate change adaptation research in socioeconomic systems

Satellite-based climate change adaptation research in socioeconomic systems still has some limitations. Most studies focus on crop monitoring under normal conditions, with limited attention to dynamic resource changes during crises such as conflicts and insufficient assessment of the spatial distribution and reuse potential of agricultural waste. Satellite-derived environmental data are rarely integrated into infectious disease transmission models, particularly for spatial risk assessments linking environmental exposure to health outcomes. Satellite-based monitoring mainly addresses spatial patterns, short-term dynamics, and disaster vulnerability, but long-term assessments of infrastructure performance, especially in the Global South, remain underdeveloped. The integration of spatial data with behavioral or demographic factors is limited; urban heat island studies often neglect variables such as humidity and wind, and comparative analyses across cities of different types and scales are lacking. Although satellites contribute to disaster monitoring, their integration with economic models for loss estimation, insurance pricing, and asset valuation remains in its infancy. The main contributions and limitations of studies Satellite-based Climate Change Adaptation Research in Socioeconomic Systems are concluded in Table D4 in Appendix D.
5 Conclusions and future direction
5.1 Conclusions
This study provides a bibliometric analysis and document review of satellite-based climate change research from 1994 to 2025, from the perspectives of mitigation and adaptation strategies, which systematically outline the development trends of satellite-based climate change research. The study shows that since 2010, satellite-based climate change research has grown rapidly, with increasing emphasis on GHG monitoring and modeling, ecosystem responses such as vegetation cover and water distribution, and the quantification of urban environmental changes and adaptation policies.
In satellite-based climate change mitigation research, satellites are mainly used to monitor CO2 and CH4, identify major emission sources such as energy and power production, and quantify their spatial and temporal dynamics. However, satellite-based non-CO2 GHG emission monitoring and quantification remain limited, especially regarding N2O emissions from agriculture, waste treatment, and industrial processes such as fertilizer use, livestock farming, landfill decomposition, and chemical manufacturing. Small-scale, spatially diffused, and informal emission sources, such as crop residue burning and scattered industrial sites, are often excluded from global inventories. Satellite-based emission monitoring and quantification has yet to be fully utilized to capture spatiotemporal emission variations across regions and sectors, constraining the identification of major emission drivers and undermining mitigation strategies in socioeconomic systems.
In satellite-based climate change adaptation research, satellites are mainly used to monitor global water resources, vegetation dynamics, and coastal changes to assess the impacts of climate change on agriculture, hydrology, forests, and sea-level rise. However, satellite-based groundwater availability monitoring, forest ecosystem health tracking, and coastal ecosystem degradation capturing still struggle with accuracy, spatial resolution, and fine-scale detection, particularly in capturing cross-regional variability and long-term trends. Comparative analyses across climate zones and temporal scales are limited. Assessments of climate risks to infrastructure, public health, and livelihoods are underdeveloped, especially in high-risk and data-scarce regions. Environmental exposures, such as heatwaves, air pollution, and water scarcity, are rarely integrated into spatial health impact assessments. Mapping of agricultural waste distribution and reuse potential remains limited. Long-term evaluations of infrastructure resilience and asset-level climate risks in the financial sector are also lacking. Satellite-based climate change adaptation research remains in its early stage, with incomplete coverage and insufficient integration across ecological and socioeconomic systems.
5.2 Future directions
By analyzing the extant studies in satellite-based climate change research, future research can be advanced in the following aspects:
Satellite-based Climate Change Mitigation in Ecosystems: Future work can address uncertainties in transport models, meteorological fields, initial conditions, and emission inventories to improve the accuracy of GHG retrieval, especially by enhancing the capacity to distinguish biogenic and anthropogenic sources in ecologically complex regions. Focus can be placed on global ecological zones such as peatlands, savannas, and arid grasslands to quantify N2O and CH4 emissions using satellite-based approaches. High-sensitivity algorithms are needed to detect small-scale, intermittent emission events such as biomass burning. High-frequency, temporally resolved source–sink inversion models based on sparse ground observations can improve attribution of fluxes. Advances in atmospheric correction, cloud filtering, and data fusion can be integrated with CTMs to generate high-resolution and stable CO2 distribution maps. Particular attention can be given to identifying long-term carbon storage trends in ecosystems vulnerable to land degradation, frequent fires, and droughts to assess potential tipping points in carbon sink capacity. Future work can also integrate multi-sensor data to improve the temporal and spatial resolution of satellite-based monitoring; combine satellite data with ground-based measurements and socioeconomic factors to refine emission estimation and source attribution; and develop high-sensitivity sensors and integrate them with global climate models to improve carbon flux tracking and uncertainty characterization.
Satellite-based climate change mitigation in socioeconomic systems: Future work can quantify GHG emissions from globally distributed but poorly monitored sectors, including cement production, chemical industries, landfill waste decomposition, and informal burning practices. It can analyze the emission profiles of these sectors across countries and their contributions to national inventories, particularly in regions lacking ground-based monitoring infrastructure. Future work can also explore spatial disparities in emission intensities across continents and evaluate how economic transitions, energy structure shifts, and urbanization influence global emission trends. A key focus is identifying high-emission hotspots in developing regions and understanding their drivers under varying development pathways. Future work can also explore satellite-based monitoring to verify national greenhouse gas and non-greenhouse gas emission inventories to obtain more accurate and comprehensive emission data, and integrate satellite-based data with corporate carbon disclosure frameworks to enhance the transparency and credibility of carbon trading and other market mechanisms.
Satellite-based Climate Change Adaptation in Ecosystems: Future work can systematically evaluate the impacts of extreme climate events, such as droughts, wildfires, and marine heatwaves, on the adaptive capacity of global ecosystems, with a focus on identifying the vulnerability of key systems, such as tropical rainforests, alpine zones, and coral reefs, under multiple climate stressors. Comparative studies across continents can be conducted to explore global ecological adaptation thresholds and potential tipping points. Efforts can prioritize the development of satellite-based indicators to monitor groundwater recharge, river flow variability, forest health including pest outbreaks and species migration, and coastal ecosystem degradation. Standardizing regional-scale assessments of water availability and long-term trends will improve the robustness of cost–benefit analyses. Coupled model–data approaches can be used to reveal forest ecosystem responses to climate extremes, and the establishment of long-term ecological monitoring data sets can support resilience assessments across diverse biomes.
Satellite-based Climate Change Adaptation in Socioeconomic Systems: Future work can expand satellite use in assessing crop losses, water allocation stress, infrastructure vulnerability, and health impacts. Focus can be placed on exposure and recovery pathways during extreme events such as floods, droughts, and heatwaves and on the mechanisms linking climate risks with socioeconomic inequality. The spatial distribution and reuse potential of agricultural waste can be evaluated to improve regional management. Drought monitoring can be enhanced through unified classification and assessment protocols. Satellite-based systems can be developed to track disease transmission by integrating environmental variables such as air quality and climate with geospatial epidemiological data. Urban adaptation research can link satellite-derived spatial data with behavioral and demographic information to anticipate infrastructure and health needs. Satellite monitoring of infrastructure, particularly in the Global South, can inform resilience planning, identifying vulnerabilities in roads, bridges, and buildings over time. Satellite data can be used to evaluate climate risks to assets and investments, track extreme events, and support insurance pricing and payout optimization. Future work can also construct high-resolution spatial risk maps to analyze the correlations among infrastructure exposure, population distribution characteristics, and the severity of climate hazards.
6 Appendix A Remote sensing satellites launched and planned globally for addressing climate change
Satellite remote sensing has played an important role in addressing climate change, evolving from early meteorological observations to the current monitoring of GHGs, extreme weather forecasting, ecological protection, and water resource management. Numerous remote sensing satellites have been launched worldwide, including the United States’ TIROS-1, the world’s first meteorological satellite, which ushered in the era of meteorological satellites. Other notable examples include Europe’s Meteosat First Generation, Japan’s GHGs Observing Satellite (GOSAT), and China’s TanSat (Carbon Satellite), all contributing to the gradual establishment of a global climate change monitoring system. As shown in Table A1, current operational remote sensing satellite systems, such as the Sentinel series and the Fengyun-3 (FY-3) series, enable coordinated observations of atmospheric components, GHG concentrations, and oceanic and terrestrial parameters, providing essential scientific data for climate change research and policy formulation.
Major countries around the world are planning to enhance remote sensing satellite systems with higher spatial and temporal resolution and improved detection capabilities to strengthen climate change mitigation efforts. For instance, the CH4 Remote Sensing LiDAR Mission (MERLIN) enhances CH4 detection precision using LiDAR technology, and the Copernicus Carbon Dioxide Monitoring Mission (CO2M) enables coordinated monitoring of CO2, CH4, and NO2. These remote sensing satellites, as shown in Table A2, promote international climate cooperation through a global remote sensing network and provide enhanced data support for global climate change mitigation and adaptation efforts.
Despite remarkable advancements in improving observation accuracy, resolution, and coverage, satellite remote sensing still faces several challenges in addressing climate change. These challenges include insufficient accuracy in concentration inversion and emission estimation, a focus on monitoring CO2 and CH4 with limited remote sensing of other important gases such as N2O, weak ground-based validation capabilities, a lack of synergy in observing GHGs and aerosols, and insufficient satellite data resolution and accuracy to capture small-scale or rapidly changing details. Long satellite revisit cycles also limit monitoring capabilities for fast-changing ecological and socioeconomic processes. Additionally, satellite data may not fully capture the impact of human activities on the environment or reflect biodiversity and ecosystem complexity. Furthermore, satellite remote sensing mainly provides surface-level information, while interactions between the surface and water bodies in socioeconomic systems, such as urban drainage systems and rivers, may not be directly captured.

8.6 C6 Institutional collaboration network
Figure C7 shows the collaboration network between institutions, with node size representing an institution’s frequency, reflecting its academic influence. The Chinese Academy of Sciences serves as the largest central node, forming a collaboration network with numerous global institutions through dense connections. Agencies such as the National Aeronautics and Space Administration, the United States Department of Agriculture, and the University of California System demonstrate distinct international collaboration clusters. Although Chinese universities like Beijing Normal University and Nanjing University maintain close ties with research institutes, their node sizes and connection scopes are smaller than those of the Chinese Academy of Sciences. The presence of institutions related to geographic sciences, space technology, meteorological administration (e.g., China Meteorological Administration), and agriculture explicitly reflects interdisciplinary collaboration dominated by Earth sciences.
