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 HiCARS 2 L2 Geolocated Ice Thickness (IR2HI2) data set contains ice thickness, surface range, surface elevation, and bed elevation measurements derived from data collected over Antarctica using the Hi-Capability Radar Sounder (HiCARS) Version 2 instrument. The data were collected by scientists working on the Investigating the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project, which is funded by the National Science Foundation (NSF) and the Natural Environment Research Council (NERC) with additional support from NASA Operation IceBridge. The data are stored in ASCII text format and are available via FTP for periodic, ongoing campaigns from 05 December 2010 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.

In the 2009/2010 season, Operation IceBridge supplemented the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project with 36 days of additional survey time. See the ICECAP Web page for more on the University of Texas ICECAP project.
