The ATLAS/ICESat-2 L3B Monthly Gridded Dynamic Ocean Topography, Version 4, and ATLAS/ICESat-2 L3B Monthly 3-Month Gridded Dynamic Ocean Topography, Version 2 data sets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), require reprocessing. Due to changes in the availability of external sea ice concentration products during ICESat-2 Release 007 reprocessing, sea ice concentration information was not read correctly from the ATL12 input products for ATL19 and ATL23. This has caused a degradation in quality of the ATL19 and ATL23 data over ice-covered regions. This issue will be addressed and the data reprocessed. Delivery of reprocessed ATL19 and ATL23 files is expected in February 2026.
