New data set released: ATLAS/ICESat-2 L3B Annual Land Ice Height

The ATLAS/ICESat-2 L3B Annual Land Ice Height, Version 1 (ATL11) data set from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data contains surface height estimates both for crossovers and for along-track reference points between crossovers. The product uses consistency checks to cull blunders from the ATL06 record, applies a local-topography correction to remove height variations due to small-scale surface slopes, and contains values that can be directly differenced to obtain height changes through time (dh/dt).
