Available at http://nsidc.org/data/nsidc-0271.html. 30 August 2006. Background: Global, monthly snow water equivalent (SWE) climatologies are generated from passive microwave brightness temperature data derived from Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) and Defense Meteorological Satellite Program (DMSP) -F8, -F11 and -F13 Special Sensor Microwave/Imager (SSM/I) radiances and gridded to the Northern and Southern 25 km Equal-Area Scalable Earth Grids (EASE-Grids).
