The NASA IceBridge ATM Level-1B Qfit 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.
