Abstract

The NO2 density error retrieved by the traditional method of differential optical absorption spectroscopy (DOAS) was analyzed. The technique for reducing the error is proposed and used to obtain the NO2 density of Chengdu through DOAS.

Key words： absorption structure; low-frequency structure; absorption cross-section; NO2 density
