This dataset contains Greenland Ice Sheet snowfall climatologies derived from Release 5, Version P1 of the CloudSat snowfall product (2C-SNOW-PROFILE: http://www.cloudsat.cira.colostate.edu/data-products/level-2c/2c-snow-profile). Before gridding, we applied a filter to the 2C-SNOW-PROFILE product which excluded all snowfall rates that were greater than two standard deviations from a 50 km running median. Snowfall climatologies were produced by (1) averaging all valid CloudSat snowfall rate observations within 45 km of the grid cell center, (2) averaging these snowfall rates for each month, and (3) averaging all months to produce a snowfall climatology for the 2006-2016 study period. We also produced seasonal snowfall climatologies by averaging monthly snowfall rates from the following periods (e.g. Spring [MAM], Summer [JJA], Autumn [SON], and Winter [DJF]). The snowfall climatologies have a WGS84 / NSIDC Sea Ice Polar Stereographic North projection (EPSG:3413) with a spatial resolution of 15 x 15 km. ...
