According to the second-generation (Moderate-resolution imaging spectroradiometer,MODIS) retrieval algorithm of aerosol properties over land (C005-L),the atmospheric correction of MODIS/Terra data at Semi-arid climate and environment observatory of lanzhou university (SACOL) of (Aerosol robotic network,AERONET) in the semi-arid region of the Loess Plateau was performed by respectively using the SACOL aerosol model based on surface observation and the continental aerosol model used in 6S. The surface reflectances of the visible and near-infrared channels of the SACOL area were obtained and the 0.66vs2.12 and 0.47vs0.66 surface reflectance relation and their change with scattering angle and vegetation index were verified. The results show that the correlation of surface reflectances between 0.47 μm and 0.66 μm is stronger and more stable than the one between 0.47 μm and 2.12 μm;the surface reflectance relation of 0.47vs2.12 μm is not dependent on scattering angle.
