IceBridge Accumulation Radar L1B Geolocated Radar Echo Strength Profiles

The documentation for this data set is currently under construction and will be available in the near future. If you have any questions regarding this data set, please contact NSIDC User Services Office either by filling out a contact form, by e-mail to, or by telephone at +1 303-492-6199.

The NASA IceBridge Accumulation Radar L1B Geolocated Radar Echo Strength Profiles(IRACC1B) 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.

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.

See the CReSIS Web page for more on the Accumulation Radar instrument.

Data are available via FTP.
