Shouxian Aerosol Radiative Properties measured by DOE AMF and Compared with CERES-MODIS

摘要

The U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program held its first mobile facility (AMF) field campaigns in Shouxian in eastern China. Based on the AMF data, we studied the radiative properties of aerosols in late autumn and early winter. The results show that aerosols and clouds decreased the surface total radiation flux (RF) by 27.5% and the shortwave (SW) RF by 30.8%. The aerosol radiative effect (ARE) in late autumn and early winter calculated is about -24.9 W/m~2. In addition, we compared the AMF data with MODIS datasets in a 1×1 degree box. The net SW errors of Terra and Aqua were 97.4 and 30.0 w/m~2. The net LW errors were 17.4 W/m~2 and 21.4 W/m~2, respectively. The differences of the errors between Terra and Aqua were caused by the different zenith angles and the different atmospheric aerosol and vapor backgrounds during the satellite overpasses.
