Layer Abstract

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, United Kingdom. Available at http://www.antarctica.ac.uk//bas_research/data/online_resources/snow_accumulation/. Accessed 27 October 2006. Background: This map of Antarctic snow accumulation is derived from a compilation of field measurements. Satellite observations from AMSR-E and AVHRR are used to guide the interpolation. Values for locations subject to snow melt may be unreliable. From this map can be obtained a value of 143 +/- 4 mm per year snow water equivalent for the average rate of snow accumulation upon the grounded ice sheet of Antarctica. Resolution: 125 km.

Server Abstract

The National Snow and Ice Data Center (NSIDC) Antarctic Cryosphere Access Portal (A-CAP) is a map server that provides data and information pertinent to the frozen regions of the Antarctic ice sheet and the Southern Ocean, including monthly climatologies of sea ice extent and concentration, ice sheet elevation and accumulation, satellite imagery, and more. In addition to providing map images and source data through Open Geospatial Consortium, Inc. (OGC) protocols--Web Map Service (WMS), Web Feature Service (WFS), and Web Coverage Service (WCS)--a dynamic Web interface for exploring these data is also available at http://nsidc.org/agdc/acap/. If you have questions, comments or suggestions, please contact NSIDC User Services at +1.303.492.6199 or nsidc@nsidc.org.
