摘要	This article calculated the blue sky albedo using MODIS shortwave Black Sky Albedo (BSA) and White Sky Albedo (WSA) data combined with the 6S radiation transfer model simulated sky scattering light proportion factors. Based on the aerosol optical depths (AOD), particle size distribution, and complex refractive index data from the AERONET station in Baotou, the 6S radiation transfer model was used to simulate the surface (SFC) and top of atmosphere (TOA) ARF from 2018 to 2021. The differences between different types of albedos (BSA and WSA) and different aerosol models ARF and the true ARF were compared. The results showed that the average TOA ARF was (1.54±3.8)W/m2, and its value was related to the surface albedo and single scattering albedo (SSA). The continental and urban TOA ARF were positive values, about 2.2 and 8.6 times the real value, respectively. The desert TOA ARF was mostly negative, and in some months with large albedo, it was positive. The average SFC ARF was (-30.39±9.5)W/m2, with lower absolute values in summer and autumn. The continental, urban and desert SFC ARF were about 1.1, 1.76 and 0.77 times the real value, respectively, and different aerosol models had little effect on SFC ARF. The results of the three wavelengths method simulation of black carbon (BC) ARF showed that the average SFC and TOA BCARF were (-6.82± 4.3)W/m2 and (2.23±1.5)W/m2, respectively, and SFC BCARF accounts for 7.3% to 40.4% of the total SFC ARF, with a higher proportion in summer. © 2023 Chinese Society for Environmental Sciences.
