New data set releases: ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height and Land Ice Height Change

The ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height, Version 1 (ATL14) and ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height Change, Version 1 (ATL15) data sets from the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) mission are available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).  These data sets bring the time-varying height estimates provided in ATLAS/ICESat-2 L3B Annual Land Ice Height (ATL11) into a gridded format. ATL14 provides a high resolution (100 m), ice sheet surface height digital elevation model (DEM). ATL15 provides coarser resolution (1km, 10km, 20km, and 40km) height-change maps at 3-month intervals. These data sets allow visualization of height-change patterns, and the calculation of integrated regional volume change.  Spatial coverage is over the north and south polar regions.  Current temporal coverage is from 14 October 2018 to 23 June 2021 and will be updated regularly.
