   Description: 
      Abstract:
         This data set comprises global, monthly satellite-derived Snow Water 
         Equivalent (SWE) climatologies from November 1978 through May 2007, with 
         periodic updates released as resources permit. Global data are gridded to the 
         Northern and Southern 25 km Equal-Area Scalable Earth Grids (EASE-Grids). 
         Global snow water equivalent is derived from Scanning Multichannel Microwave 
         Radiometer (SMMR) and selected Special Sensor Microwave/Imagers (SSM/I). 
         Northern Hemisphere data are enhanced with snow cover frequencies derived from 
         the Northern Hemisphere EASE-Grid Weekly Snow Cover and Sea Ice Extent Version 
         2 data (these data were not produced for the Southern Hemisphere). These data 
         are suitable for continental-scale time-series studies of snow cover and water 
         equivalent. The data are binary data files and PNG images, and are available 
         via FTP.
