Version 4 of the MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). New for this version:
NSIDC would like to announce a change to data access for the MEaSUREs InSAR-Based Antarctica Ice Velocity Map, Version 2 data set. Data access is now solely through our primary portal at: https://n5eil01u.ecs.nsidc.org/MEASURES/NSIDC-0484.002/. File level spatial and temporal metadata have been added to aid in searching the data.

NSIDC would like to announce new data available for the MEaSUREs Greenland Ice Sheet Velocity Map from InSAR Data, Version 2 data set. Seasonal (winter) velocity maps for 2014/15, 2015/16, and 2016/17 from TSX/TDX and Sentinel-1 are now available. This data is posted at both 500 m and 200 m resolution. This release also includes the addition of full record ancillary shapefiles that contain information about the satellite tracks used to produce the mosaics as well as browse images of the magnitudes.
Field data from the Soil Moisture Active Passive Validation Experiment 2015 (SMAPVEX15) validation campaign are now available at the National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The new data set is the first of many for the SMAPVEX15 campaign and contains brightness temperatures obtained by the Passive Active L-band System (PALS) aircraft instrument.
The F13 data from the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 1 data set is now available at version 1.2. The minor change in this version corrects the handling of QC flags to retain more data, eliminating only the flagged data in a given channel and taking care not to eliminate data in other channels.

NOAA@NSIDC is pleased to announce the release of Version 3 of the NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration (final CDR). The reason for the version change is to update the masks used to remove spurious ice in the Northern Hemisphere. The masks changed from sea surface temperature climatology-based masks to the Polar Stereographic Valid Ice Masks Derived from National Ice Center Monthly Sea Ice Climatologies.
