Direct Radiative Effect of Absorbing Aerosols: Sensitivity to Mixing State, Brown Carbon, and Soil Dust Refractive Index and Shape

Abstract

Key Points Aerosol absorption is sensitive to mixing state, brown carbon, and soil dust optical properties Blanching reduces coating brown carbon radiative effect; soil dust radiative effect uncertainty due to the refractive index is large Radiative effect of radiation‐absorbing aerosol total uncertainty is mainly due to dust refractive index and brown carbon treatment
