Comparison of Aerosol Radiative Forcing Observed by AERONET and MODIS at Xianghe Station | Comparison of the Aerosol Product and Its Radiative Forcing between AERONET and MODIS

This paper presents aerosol optical depth (AOD) data and aerosol radiative forc- ing 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 over- estimation of aerosol radiative forcing than AERONET one, e.g., 12{17Wm i2 on the ground, 2{3Wm i2 on the top of atmosphere, and 9{12Wm i2 in the atmosphere respectively.
