There is concern that sea level rise due to a decrease in the mass of the Antarctic ice sheet will occur as a result of ongoing global warming. In order to predict the future of Antarctic ice sheet mass change, it is necessary to quantitatively understand the individual processes involved. Precipitation is the primary input of mass to the Antarctic ice sheet, but our knowledge of Antarctic precipitation amounts and systems is still limited. Observations are essential to address this challenge, and expectations for satellite observations are particularly high. This presentation will present what is known about Antarctic precipitation and the challenges that need to be addressed, and will discuss research that can be carried out with EarthCARE data.
