The ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height (ATL14) and ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height Change (ATL15) data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated to Version 3. 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 is a high-resolution (100 m) digital elevation model that provides spatially continuous gridded data of ice sheet surface height. ATL15 provides coarser resolution (1 km, 10 km, 20 km, and 40 km) height-change maps at 3-month intervals, allowing for visualization of height-change patterns and calculation of integrated regional volume change. Spatial coverage is global. Temporal coverage currently spans cycles 3 through 18.
