The ICESat-2 L4 Along-Track Sea Ice Thickness, Version 1 (IS2SITDAT4) data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include data for April 2022. This data set reports daily, along-track winter sea ice thickness across the Arctic Ocean. Sea ice thickness is estimated using ATLAS/ICESat-2 L3A Sea Ice Freeboard (ATL10), Version 5 data and NASA Eulerian Snow On Sea Ice Model (NESOSIM) snow loading. The temporal coverage now spans 14 October 2018 to 30 April 2022.
