Reconciliation of modeled and observed aerosols and radiative fluxes is a major research topic. Su et al.  use radiative kernels to link the model biases in the aerosol optical depth and land surface albedo to the model bias in top-of-atmosphere clear-sky reflected shortwave fluxes. Accounting for the aerosol optical depth and land surface albedo contribution to the shortwave flux reduces the modeled shortwave flux bias by 25 per cent and 70 per cent over ocean and land.
This study highlights the importance of correcting the land surface albedo and constraining the aerosol optical depth in the AeroCom models by using satellite observations. The authors recommend that all models should use observation-based land surface albedo as an input.
