| Abstract: | The method of remote sensing aerosols using MODIS data is introduced. The aerosol products from MODIS are compared with the results from the sun photometer observations at Peking University. The two data series fit very well with high correlations. Some pictures are shown which described the aerosol optical depth (AOD) distribution over Beijing. We found that the remote sensing from space had provided us a new way to understand the regional air pollution better, and the AOD data from satellite observations filled up the shortcoming of the data from ground observations with limited spatial coverage. Aerosol data from space are useful not only to the research on global and regional climate but also to the analysis of urban pollution. |
