Abstract :
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.
