	            This data set provides a 1 km resolution Digital Elevation Model (DEM) of 
	            Antarctica. The DEM combines measurements from the European Remote Sensing 
	            Satellite-1 (ERS-1) Satellite Radar Altimeter (SRA) and the Ice, Cloud, and 
	            land Elevation Satellite (ICESat) Geosciences Laser Altimeter System (GLAS). 
	            The ERS-1 data are from two long repeat cycles of 168 days initiated in March 
	            1994, and the GLAS data are from 20 February 2003 through 21 March 2008. The 
	            data set is approximately 240 MB comprised of two gridded binary files and two 
	            Environment for Visualizing Images (ENVI) header files viewable using ENVI or 
	            other similar software packages. The data are available via FTP.
