GLAS/ICESat L1A Global Engineering Data
The Geoscience Laser Altimeter System (GLAS) instrument on the Ice, Cloud, and Land Elevation Satellite (ICESat) provides global measurements of polar ice sheet elevation to discern changes in ice volume (mass balance) over time. Secondary objectives of GLAS are to measure sea ice roughness and thickness, cloud and atmospheric properties, land topography, vegetation canopy heights, ocean surface topography, and surface reflectivity. GLAS has a 1064 nm laser channel for surface altimetry and dense cloud heights, and a 532 nm lidar channel for the vertical distribution of clouds and aerosols. Level-1A global engineering data (GLA03) include satellite housekeeping data used to calibrate data values for GLA01 and GLA02. Data are in scaled integer binary format, big-endian (Unix) byte order, and are available via FTP.
