The NASA IceBridge Narrow Swath ATM Level-1B Qfit Elevation and Return Strength (ILNSA1B) data set contains spot elevation measurements of Greenland, Arctic, and Antarctic sea ice acquired using the NASA Airborne Topographic Mapper (ATM) 4CT3 narrow scan instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns. The data are stored in qfit binary format and are available via FTP for periodic, ongoing campaigns from 16 March 2011 to the present.
