Group: Summary

   This data set provides measurements of sea ice freeboard and sea ice thickness 
   for the Arctic region. The data were derived from measurements made by from 
   the Ice, Cloud, and land Elevation Satellite (ICESat) Geoscience Laser 
   Altimeter System (GLAS) instrument, the Special Sensor Microwave/Imager 
   (SSM/I), and climatologies of snow and drift of ice. The data span fifteen 
   GLAS campaigns, laser 1 through 3k, from 20 February 2003 to 19 October 2008. 
   Data parameters include sea ice freeboard and thickness measured in meters 
   derived from GLAS Release 28 data. The data are provided in four formats: 
   ASCII track data derived from binary track data, binary gridded polar 
   stereographic data derived from ASCII gridded polar stereographic files, 
   GeoTIFF images files, and Portable Network Graphic (PNG) image files. Also 
   included are mask files used in preparation of the image files, a Mapx grid 
   definition file, and grid cell center latitude and longitude files. The ASCII 
   track data vectors of position and ice thickness have a resolution of about 
   170 meters in the along-track direction. The binary gridded polar 
   stereographic data have a resolution of 25 km.
