Abstract:
This data set provides measurements of sea ice freeboard and sea ice thickness for the Arctic region. The data were acquired 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 six GLAS Release-28 campaigns, laser 3D through 3I, from 21 October 2005 to 05 November 2007. Data parameters include sea ice freeboard and thickness measured in meters. The data are provided in three formats: ASCII track data derived from binary track data, binary gridded polar stereographic data derived from ASCII gridded Polar Stereo 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. The data set is approximately 940 megabytes. The data are available via FTP.
