This publication Understanding top-of-atmosphere flux bias in the AeroCom Phase III models: a clear-sky perspective aims to better understanding of the bias in the comparison between the satellite retrievals of aerosols and the AeroCom models. In the paper Su et al. (2021), the biases in top-of-atmosphere reflected shortwave fluxes are related to biases in aerosol optical depth and surface albedo by using radiative kernels methodology. The first results indicates that biases in both, aerosol optical depths and land surface albedo can explain significant amount of the SW flux biases on both global and regional scales. The paper also highlights that AeroCom model simulations can be improved with the use of observation-based land surface albedo. This paper has been highlighted by EOS journal
