Abstrakt: We present experiments carried out in the Large Aerosol Chamber of Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, during 2021–2022 to study the optical characteristics of smoke aerosol with a long aging time (up to 2–3 days). We estimated how the smoke evolution influences the smoke aerosol radiative forcing (ARF) at the top of atmosphere in the Arctic in summer time. It is shown that for smoldering smokes, the main factor that determines the time dependence of ARF is the evolution of the aerosol optical depth; while for mixed smokes, it is also necessary to take into account the time variations in the single scattering albedo of aerosol particles. The dependence of ARF on underlying surface types and illumination conditions typical for the Arctic is considered for different biomass burning modes. [ABSTRACT FROM AUTHOR]
