Abstract:
The Antarctic snow accumulation map is derived from a compilation of field measurements. Satellite observations from AMSR-E and AVHRR (Advanced Microwave Scanning Radiometer-EOS and Advanced Very High Resolution Radiometer) instruments are used to guide the interpolation. The effective resolution of the map is approximately 100 km. The estimates of root mean square percentage error apply to regional averages at scales of around 100 km by 100 km. On smaller scales, additional deviations of 30% r.m.s. are likely. Values for locations subject to melt may be unreliable. Units are (kg/m2/a), or (mm/a) water equivalent.
