Reducing the Southern Ocean shortwave bias through improved representations of Marine Boundary Layer Mixing

Abstract

ICON displays a significant radiative bias in the Southern Ocean (SO), which is attributed to an underestimation of boundary layer clouds. This has been mitigated in the SO mid-latitudes by altering the triggering of shallow convection (SC) and thus boundary layer mixing in ICON. Here, we use vertically resolved measurements obtained from SO field campaigns to assess the representation of boundary layer structure and cloud radiative properties for different representations of boundary layer mixing.
