摘要
This paper presents aerosol optical depth (AOD) data and aerosol radiative forcing obtained from AErosol RObotic NETwork (AERONET) and Moderate resolution Imaging Spectroradiometer (MODIS) from September 2004 to September 2005 at Xianghe, China. The results show that aerosol optical depth derived from MODIS has good agreement with AERONET observation at Xianghe station through this period. In average, MODIS AOD showed a small systematical overestimation than that of AERONET. The higher MODIS AOD also results overestimation of aerosol radiative forcing than AERONET one, e.g., 12-17 Wm(-2) on the ground, 2-3 Wm(-2) on the top of atmosphere, and 9-12 Wm(-2) in the atmosphere respectively.
