The documentation for this data set is currently under construction and will be available in the near future.

The NASA IceBridge Sigma Space Photon Counting Lidar L2 Geolocated Nadir Photon Elevations (ILSNP2) data set contains geolocated surface elevation data captured over Antarctica using the Sigma Space photon counting lidar. Along track and across track range vector location data are included. 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 ASCII text files and are available via FTP for periodic, ongoing campaigns from 29 November 2011 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.
NASA Operation IceBridge supplements the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project with additional days of survey time. See the ICECAP Web page for more on the University of Texas ICECAP project.
