Seasonal variability of shallow cumuliform snowfall: A CloudSat perspective
Cumuliform snowfall seasonal variability is studied using a multi-year CloudSat snowfall rate and cloud classification retrieval dataset. Microwave radiometer sea ice concentration datasets are also utilized to illustrate the intimate link between oceanic cumuliform snowfall production and decreased...
