The Contribution of Drifting Snow to Cloud Properties and the Atmospheric Radiative Budget Over Antarctica
International audience The Antarctic Ice Sheet experiences perpetual katabatic winds, transporting snow, and moisture from the interior towards the periphery. However, the impacts of Antarctic moisture and drifting snow on cloud structure and surface energy fluxes have not been widely investigated....
