Regional trend analysis of the aerosol optical depth comparing to MODIS and MISR aerosol products

This paper analyzes the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Multiangle Imaging Spectroradiometer (MISR) AOD products to study aerosol distribution and regional trends during 2002 to 2010. Firstly, we compared MODIS and MISR AOD with AERONET station AOD. MISR has been found the better correlation (R= 0.93), which dominate MISR perform better than MODIS over eastern China. Our study found that the spatial distribution of aerosol for both sensors is highly associated with human activities. The trend analysis shows that increasing trends are found over study areas and MISR has better applicable over eastern China is evidenced using method of trend evaluation.
