   Description: 
      Abstract:
         The NASA IceBridge ATM Level-1B Elevation and Return Strength (ILATM1B) data 
         set contains spot elevation measurements of Arctic and Antarctic sea ice, and 
         Greenland, Antarctic Peninsula, and West Antarctic region ice surface acquired 
         using the NASA Airborne Topographic Mapper (ATM) instrumentation. The data 
         were collected as part of Operation IceBridge funded aircraft survey 
         campaigns, and are stored in qfit binary format and are available for 
         periodic, ongoing campaigns from 31 March 2009 to the present via FTP.
