NASA IceBridge BedMachine Greenland Version 3 data are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Version 3 includes ocean bathymetry all around Greenland based on data from NASA’s Ocean Melting Greenland (OMG) and other campaigns of bathymetry measurements. The subglacial bed topography has also been updated by including more ice thickness data and constraining the ice thickness at the ice/ocean interface based on bathymetry data when available.

The F14 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.
This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
NSIDC DAAC would like to announce a change to data access for the MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, Version 1 data set. Direct download data access has changed for this data set to https://daacdata.apps.nsidc.org/pub/DATASETS/nsidc0481_MEASURES_greenla…, which allows files to be contained in folders by subregion. Data is still available for searching and ordering in Earthdata Search.

The MEaSUREs Greenland Image Mosaics from Sentinel-1A and 1B, Version 2.1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) with a minor version update and July 2017 data. For version 2.1, Sentinel-1, track 83 was added to the data beginning with the May 2017 mosaic. This new track improves coverage in the southern part of the ice sheet.
This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
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:
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.
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.
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.
