The NASA IceBridge ATM L0 Raw Ranges (ILATM0) data set contains raw elevation range measurements using the NASA Airborne Topographic Mapper (ATM) instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns, are stored in binary format, and are available via FTP for periodic, ongoing campaigns from 16 October 2009 to the present.
Operation IceBridge products may include test flight data that are not useful for research and scientific analysis. Test flights usually occur at the beginning of campaigns. Users should read flight reports for the flights that collected any of the data they intend to use. Check IceBridge campaign Flight Reports for dates and information about test flights.
The directory structure for this data set is described in the 00README.txt file.
