Data set update: ICESat-2 L4 Monthly Gridded Sea Ice Thickness, Version 2

The temporal coverage for the ICESat-2 L4 Monthly Gridded Sea Ice Thickness, Version 2 (IS2SITMOGR4) data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been extended to include data for April 2022.  Additionally, the March 2022 file has been reprocessed to include additional data.  If you downloaded the March 2022 file prior to 01 November 2022, please download it again to replace the previous file.

This data set reports monthly, gridded winter sea ice thickness across the Arctic Ocean. Sea ice thickness is estimated using ATLAS/ICESat-2 L3A Sea Ice Freeboard (ATL10), Version 4 data and NASA Eulerian Snow On Sea Ice Model (NESOSIM) snow loading.  The temporal coverage now spans 01 November 2018 to 30 April 2022.
