Abstract: Abstract: Climate models predict Antarctic precipitation to increase during the 21st century, but their present day Antarctic precipitation differs. A model-independent climatology of the Antarctic precipitation characteristics, such as snowfall rates and frequency, is needed to assess the models, but was not available so far. Satellite observation of precipitation by active spaceborne sensors has been possible in the polar regions since the launch of CloudSat in 2006. Here we use two CloudSat products to build the first multi-year model-independent climatology of Antarctic precipitation. The first product is used to determine the frequency and the phase of precipitation, while the second product is used to assess the snowfall rate. The mean snowfall rate from August 2006 to April 2011 is 171 mm/year over the Antarctic ice sheet north of 82°S. While uncertainties on individual precipitation retrievals from CloudSat data are potentially large, the mean uncertainty should be much smaller but cannot be easily estimated. There are no in situ measurements of Antarctic precipitation to directly assess the new climatology. However distributions of both precipitation occurrences and rates generally agree with the ECMWF ERA-Interim dataset, the production of which is constrained by various in situ and satellite observations but did not use any data from CloudSat. The new dataset thus offers unprecedented capability to quantitatively assess Antarctic precipitation statistics and rates in climate models.
