New version available: ATLAS/ICESat-2 L3B Annual Land Ice Height Version 2

The ATLAS/ICESat-2 L3B Annual Land Ice Height, (ATL11) data set from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission has been updated to Version 2 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). Version 2 contains minor changes from Version 1, including calculating all crossovers (including near 88 S). ATLAS/ICESat-2 L3B Annual Land Ice Height (ATL11)
