The MEaSUREs ITS_LIVE Landsat Image-Pair Glacier and Ice Sheet Surface Velocities, Version 1 and MEaSUREs ITS_LIVE Regional Glacier and Ice Sheet Surface Velocities, Version 1 data sets, are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These datasets consist of glacier and ice sheet surface velocities generated from Landsat 4, 5, 7, and 8 imagery.
Users of MODIS Terra and Aqua data from the NASA National Snow and Ice Data DAAC should be aware that a Science Mission Directorate (SMD) Request for Information (RFI) was released on September 8, 2022 by the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES). This RFI seeks input from the science community that will be considered in the development and implementation of a Terra, Aqua, and Aura (T, A, & A) Drifting Orbits workshop planned for later this calendar year.   
The Likely Basal Thermal State of the Greenland Ice Sheet data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to Version 2.
The IceBridge BedMachine Greenland data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to Version 5.
The Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Passive Microwave Data, Version 2 data set is now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). With Version 2, the data are now provided in NetCDF format. Links to scripts that convert the NetCDF back to the original binary format are available in the data set documentation. The Version 1 data in binary format will remain available until 31 January 2023.
The VIIRS instrument was returned to operational mode on 10 August 2022 and data are now available from 11 August 2022 onward. There may be gaps until the reprocessing is complete and all data lost while the SNPP spacecraft was in safe mode are non-recoverable. This results in a temporal coverage gap from 26 July 2022 through 10 August 2022.
The temporal coverage of the Lagrangian Snow Distributions for Sea-Ice Applications, Version 1 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been extended through 31 July 2021.
Version 4 of the ATLAS/ICESat-2 L3B Annual Land Ice Height (ATL11) and ATLAS/ICESat-2 L3A Ocean Surface Height (ATL12) data sets, will be retired from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) on 23 September 2022.
On Monday August 8, 2022 the SMAP observatory entered a safe-mode which is designed to maintain its essential functions but stops science data acquisition. The Project team is investigating the cause of the anomaly and actively working on resuming operations and continued science data acquisition. The NSIDC DAAC archive will not have science data products during this period. However, generation of the model-based Level-4 products continues until further notice without SMAP observations.
NOAA@NSIDC is pleased to announce the release of the U.S. National Ice Center Arctic and Antarctic Sea Ice Charts in SIGRID-3 Format, Version 1 data set. This data set contains Arctic and Antarctic-wide sea ice charts that have information on sea ice concentration, stage of development (often called ice type), and form. The charts are produced by the U.S. National Ice Center, with a temporal coverage of 2003 to present, and for most of the record the charts are weekly in frequency.
The Sea Ice Trends and Climatologies from SMMR and SSM/I-SSMIS, Version 3 data set, available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been extended through 31 December 2021. This data set contains sea ice concentrations, ice-covered area, ice persistence, and sea ice extent for the Arctic and Antarctic.
Update: SNPP spacecraft/VIIRS instrument in Safe Mode July 26 - August 9, 2022
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
The Northern Hemisphere EASE-Grid 2.0 Weekly Snow Cover and Sea Ice Extent, Version 4 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 31 December 2021.
The Near-Real-Time DMSP SSM/I-SSMIS Pathfinder Daily EASE-Grid Brightness Temperatures, Version 2 data set will be retired on 31 August 2022.
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 the period from 1 September 2021 to 31 March 2022.
The MEaSUREs Greenland Ice Velocity: Selected Glacier Site Single-Pair Velocity Maps from Optical Images, Version 1 data set is now available
The IceBridge Mission Flight Reports, Version 1 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include flight reports from the 2019 summer Arctic campaign.
Version 3 of the ATLAS/ICESat-2 L3B Weekly Gridded Atmosphere (ATL16) and ATLAS/ICESat-2 L3B Monthly Gridded Atmosphere (ATL17) data sets, will be retired from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) on 18 August 2022. After this date, access to the data will no longer be available, but the data set documentation will remain available for future reference. Version 4 of each data set was released on 21 February 2022.
The ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series (ATL11), Version 5 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include data from cycle 14 of the ATLAS/ICESat-2 mission. This data set provides time series of land-ice surface heights derived from the ICESat-2 ATL06 Land Ice Height product.
