Group: Summary

   This Level-3 Equal-Area Scalable Earth-Grid (EASE-Grid) Brightness Temperature 
   data set, collected since 09 July 1987, is a part of the NOAA/NASA Pathfinder 
   Program. The data set consists of gridded data from the Special Sensor 
   Microwave/Imager (SSM/I) and the Special Sensor Microwave Imager/Sounder 
   (SSMIS) in three equal-area projections: Northern Hemisphere, Southern 
   Hemisphere, and full global. The data gridding technique maximizes the 
   radiometric integrity of the original brightness temperature values, maintains 
   high spatial and temporal precision, and involves no averaging of original 
   swath data. Spatial coverage is global and a spatial resolution of 25 km is 
   available for all channels. Channels at 85 and 91 GHz are also provided at 
   12.5 km. For a given projection, there are 18 brightness temperature files per 
   day and two corresponding time files. Data are contained in flat binary files 
   and are available via FTP as processing is completed.

    Removed temporal coverage end date. Like NSIDC-0001, these data are processed 
   every quarter and temporal coverage is updated here instead of in the
