IceBridge Sigma Space Photon Counting Lidar L1B Time-Tagged Nadir Photon Ranges

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 L1B Time-Tagged Nadir Photon Ranges (ILSNP1B) data set contains nadir photon counting data captured over Antarctica using the Sigma Space photon counting lidar. Position and orientation 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 stored in compressed tar (.tgz) files and are available via FTP for periodic, ongoing campaigns from 25 November 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.

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.

Data are available via FTP.
