  <Summary>The NASA IceBridge Accumulation Radar L1B Geolocated Radar Echo Strength Profiles data set contains radar backscatter measurements of snow depth, internal layering, and topography of Greenland acquired using Accumulation Radar.  The data files are in binary format and associated GPS files are provided in MATLAB format and Applanix output format.  Also included are JPEG image files and KML files.  The data were collected as part of Operation IceBridge funded campaigns, and are available for periodic, ongoing campaigns from 05 May 2010 to the present via FTP.</Summary>
