Application of CCD data of HJ-1 satellite in PM10 evaluation in Shenzhen, China

The main missions of HJ-1 satellite are to monitor pollution, ecosystem destruction and natural disasters. In recent years, Inhalable particle (PM₁₀) has become the primary pollutant of major cities in China, which seriously affects the living environment of its residents. In this paper, we made use of high-resolution CCD data of HJ-1 satellite to monitor atmospheric inhalable particle (PM₁₀) in Shenzhen. Firstly, we inversed the aerosol optical depth (AOD) of CCD data of HJ-1 satellite. Then we analyzed the correlation between AOD and PM₁₀ using PM₁₀ data in six districts of Shenzhen and the AOD data. The conclusions are as follows. 1) The AOD and PM₁₀ are significantly related in spring-summer. 2) The correlation between AOD and PM₁₀ has been improved greatly after considering the variation of aerosol scale height.
