NSIDC has discovered some large data gaps in the 2018 F18 Brightness Temperature record affecting the DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures, Version 5 data set. Northern and Southern Hemisphere data files from 10 February through13 March 2018 and from 30 September through 31 October 2018 may contain only zero values. NSIDC is investigating the issue and will reprocess data files once the problem has been identified.
The Sea Ice Trends and Climatologies from SMMR and SSM/I-SSMIS, Version 3 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 31 December 2018. This data set contains sea ice concentrations, ice-covered area, ice persistence, and sea ice extent for the Arctic and Antarctic.
The data access locations for multiple passive microwave data sets, available through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have changed. Users accessing these data through a script will need to update accordingly. The new data access URLs are provided below:

The SMAP Level-2 and Level-3 standard and enhanced radiometer soil moisture data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated. The optional Dual Channel Algorithm (DCA) in the Level-2 products has been replaced by the Modified Dual Channel Algorithm (MCDA). The baseline algorithm (SCA-V) remains unchanged for both Level-2 and Level-3 products. Other primary changes include:
The MEaSUREs Greenland Image Mosaics from Sentinel-1A and -1B, Version 2 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated with mosaics through May 2019. This data set is produced under the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program and contains 6-day and 12-day 50 m resolution image mosaics of the Greenland coastline and ice sheet periphery.
NOAA@NSIDC is pleased to announce that the NOAA@NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 3 data set is now available through 2018. This data set provides a Climate Data Record (CDR) of sea ice concentration from passive microwave data. It provides a consistent, daily and monthly time series of sea ice concentrations from 09 July 1987 through 31 December 2018 for both the north and south polar regions on a 25 km x 25 km grid.
The VIIRS/NPP Snow Cover Daily L3 Global 375m SIN Grid, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). T
The Nimbus-7 SMMR Derived Monthly Global Snow Cover and Snow Depth, Version 1 data set will be retired from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) on 27 August 2019. After this date, the data will no longer be accessible, but the data set documentation will remain available for future reference.
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 2018. This data set contains snow cover and sea ice extent derived from SMMR and DMSP-F8, -F11, -F13, and -F17 SMM/I and SSMIS brightness temperature measurements. These data are provided on the 25 km Northern Hemisphere EASE-Grid 2.0.
The MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from Optical Images, Version 2 data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to include all available data from 1985 through 2018 for all regions. Additionally, the sensor name abbreviations in the .meta files have changed. This data set consists of mean monthly velocity maps for selected glacier outlet areas from 1 March 1985 through 31 December 2018.
The MEaSUREs Greenland Annual Ice Sheet Velocity Mosaics from SAR and Landsat, 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 data for 2018.
The SMAP Radiometer Twice-Daily rSIR-Enhanced EASE-Grid 2.0 Brightness Temperatures, 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 contains twice-daily brightness temperature data derived from the SMAP radiometer and applies the same Scatterometer Image Reconstruction (SIR) technique used to derive brightness temperatures from the SMMR, AMSRE, and SSM/I-SSMIS sensors.
The SMAP satellite returned to science mode and resumed collecting science data on 23 July 2019 at 22:28 UTC. These data are now available. The SMAP science team has completed a preliminary data assessment and flagged the first ~25 seconds for quality concerns, as described in this advisory note.
The SMAP satellite returned to science mode and resumed collecting science data on 23 July 2019 at 22:28 UTC. However, data collected and processed after 23 July 2019 will not be available until the SMAP science team completes a data quality assessment. NSIDC will continue to provide updates as we gain a better understanding of data availability.
The MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, 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 data from December 2018 and January 2019.
