Arthern, R.J., D.P. Winebrenner, and D.G. Vaughan. 2006. Antarctic snow accumulation mapped using polarization of 4.3-cm wavelength microwave emission. Journal of Geophysical Research. 111, D06107, doi:10.1029/2004JD005667. Data provided by the British Antarctic Survery, Cambridge, UK. Available at http://www.antarctica.ac.uk/Resources/PSD/snow_accumulation/. 27 October 2006. Background: The map of Antarctic snow accumulation is derived from a compilation of field measurements. Satellite observations from AMSR-E and AVHRR 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. From this map we obtain a value of 143 +/- 4 mm per year for the average rate of snow accumulation upon the grounded ice sheet of Antarctica.
