The Near Real-Time VIIRS/JPSS-1 L3 Global Daily 500m SIN Grid Snow Cover, Grain Size, and Dust Radiative Forcing, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set includes parameters from two different algorithms: snow fraction, snow grain size, vegetation fraction, rock fraction, ice fraction, and shade fraction from the SCAG algorithm and snow darkening, radiative forcing, and snow grain size from the DRFS algorithm.
The SMOS-Based SMAP L2 Radiometer Half-Orbit 9 km EASE-Grid Soil Moisture and SMAP/SMOS L3 Radiometer 9 km EASE-Grid Soil Moisture, Version 2 datasets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated through 9 October 2026.
IceBridge BedMachine Greenland, Version 7 is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains a bed topography and bathymetry map of Greenland, as well as surface elevation and ice thickness data. This version of the dataset uses Ice Flow Perturbation Analysis to better reconstruct the bedrock topography beneath the ice sheet.
Data from the SMAP Standard products, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been reprocessed from 14 May 2026 to 28 July 2026 to correct for a geolocation issue discovered in August 2026. We recommend that users who previously downloaded data from that time period redownload the corrected files.
ATLAS/ICESat-2 L3A Along Track Coastal and Nearshore Bathymetry, Version 1 will be retired from the NSIDC DAAC on 23 November 2026. Upon retirement, data will no longer be accessible, but all related documentation will remain available on the data set’s web page for future reference. We recommend using the latest version of these data sets, found under the “more recent version” link on the web pages.
ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height, Version 6 (ATL14) and ATLAS/ICESat-2 L3B Gridded Antarctic and Arctic Land Ice Height Change, Version 6 (ATL15) are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The ATL14 data set contains 100m DEM models of land ice height, while ATL15 has varying spatial resolutions of land ice height change in the same regions.
The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is pleased to announce that the OpenAltimetry web application has been updated to include ATLAS/ICESat-2 Nearshore Bathymetry, Version 2 (ATL24).
Delivery of science data products from the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite is expected to cease at 13:00 Universal Time (UTC) on November 2, 2026. After this date, access to the historical data and documentation will still be available, but delivery of new S-NPP VIIRS data sets into the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) will cease.
The Bootstrap Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS, Version 4 dataset, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has stopped forward processing. The final temporal coverage for the data is 1 November 1978 to 31 December 2025. The data will remain available for download as a static product at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
ICESat-2 Cal/Val 2022 L2 CHIR Green Wavelength Lidar Arctic Sea Ice Heights and Bathymetry, Version 1 is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains Arctic summer sea ice heights and bathymetry with the primary purpose to evaluate the positional accuracies of NASA’s ICESat-2 ATLAS measurements.
The National Snow and Ice Data Center (NSIDC) has released Version 2 of the Canadian Ice Service Arctic Regional Sea Ice Charts in SIGRID-3 Format data set. The ice charts have information on ice concentration, stage of development, and ice form. This new version extends the data record from 1 January 2006 back to 25 June 1968 through the present at a weekly temporal resolution.The main changes in Version 2 include the following:
The AMSR2 satellite-based data products, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), will continue forward processing, as the data remain available from the Japan Aerospace Exploration Agency (JAXA). NSIDC is planning for the development of AMSR3 data products in 2027, but AMSR2 data products will continue to be available until JAXA ends processing. NSIDC is planning to develop AMSR3 data products in the future. The NSIDC AMSR2 satellite-based data products include:
The Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 2 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has had forward processing paused from 2 September 2026 to 3 September 2026 due to system updates.
The CryoSat-2 Level-4 Sea Ice Elevation, Freeboard, and Thickness, Version 1 (RDEFT4), and CryoSat-2 Level-1B Waveforms, Sea Ice Elevation, and Surface Roughness, Version 1 (RDWES1B) data sets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), are complete and will no longer receive further updates.
The ICESat-2 L4 Monthly Gridded Sea Ice Thickness, Version 4 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated. The temporal coverage has been extended by adding the monthly files from September 2025 through April 2026.Data set DOI: https://doi.org/10.5067/TXDHDJ1JT0CG
The SMAP Standard and Near Real-Time data sets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), experienced a geolocation issue from 14 May 2026 to 28 July 2026. All Standard products for that time period are currently being reprocessed and will be replaced in the coming weeks. Near Real-Time products will not be replaced.
The DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures, Version 6 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 5 July 2026. This data set provides daily gridded brightness temperatures derived from passive microwave sensors and distributed in a polar stereographic projection.
ICESat-2 Calibration/Validation LVIS L3A Sea Ice Freeboard, Version 1 is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains high-resolution sea ice freeboard estimates derived from airborne measurements collected over the Arctic Ocean.
The SMOS-Based SMAP L2 Radiometer Half-Orbit 9 km EASE-Grid Soil Moisture, Version 2 and SMOS/SMAP L3 Radiometer 9 km EASE-Grid Soil Moisture, Version 2 data sets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated to version 2.
High Mountain Asia MODIS/Terra L3 Daily 500m SIN Grid Spatially and Temporally Complete (STC) Snow Cover and Snow Surface Properties, Version 1 is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains spatially and temporally complete (STC) raster images of snow cover and snow surface properties from 1 October 2000 through 30 June 2022 for the High Mountain Asia region.
