Multiple Level-1B, Level-2A, and Level-3A data sets from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission have been updated to Version 3 at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These data sets provide: telemetry data; geolocated photon data; backscatter profiles; atmospheric layer characteristics; and geolocated surface elevations for land ice, land and vegetation, and ocean surface. The temporal coverage of the data sets begins on 13 October 2018, and there may be gaps in the temporal and spatial coverage due to processing lags. These gaps are expected to be filled in the coming weeks.
The ICESat-2 version 1 data sets are being retired as the version 3 data sets are released.
