EOSDIS Data News: October 13, 2017

NSIDC DAAC

NASA's National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has published the dataset Snow Experiment 2017 (SnowEx17) SnowMicroPen (SMP) Raw Penetration Force Profiles. This dataset contains raw penetration force profiles measured at snow pits and along linear transects at Grand Mesa, Colorado using the SMP, a digital snow penetrometer. The NASA SnowEx17 campaign was conducted in Colorado in February 2017.

NSIDC DAAC has published the dataset NASA IceBridge BedMachine Greenland, Version 3. Version 3 includes ocean bathymetry all around Greenland based on data from the 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.

NSIDC DAAC has published the dataset Making Earth System Data Records for Use in Research Environments (MEaSUREs) Greenland Annual Ice Sheet Velocity Mosaics from synthetic aperture radar (SAR) and Landsat, Version 1. This dataset, part of the MEaSUREs Program, contains annual ice velocity mosaics for the Greenland Ice Sheet derived from SAR data obtained by TerraSAR-X/TanDEM-X (TSX/TDX) and Copernicus Sentinel-1A and -1B satellites, and from Landsat 8 optical imagery for years 2015 and 2016.

NSIDC DAAC would like to announce a change to data access for the MEaSUREs Multi-year Greenland Ice Sheet Velocity Mosaic, Version 1 dataset. Data access is now solely available through our primary archive at: https://n5eil01u.ecs.nsidc.org/MEASURES/NSIDC-0670.001/. File level spatial and temporal metadata have been added to aid in searching and ordering the data through Earthdata Search.

NSIDC DAAC has published Scanning Multichannel Microwave Radiometer (SMMR) data to the dataset MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily Equal-Area Scalable Earth (EASE)-Grid 2.0 Brightness Temperature Earth Science Data Record (ESDR), Version 1. Also, the Special Sensor Microwave Imager/Sounder (SSMIS) F10 data from this dataset 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 dataset is part of the MEaSUREs Program.

NSIDC DAAC has published new data for August 2017 to the dataset MEaSUREs Greenland Image Mosaics from Sentinel-1A and 1B, Version 2 . The mosaics are derived from C-band SAR (C-SAR) acquired by the Copernicus Sentinel-1A and -1B imaging satellites between January 2015 and August 2017.

This dataset is part of the MEaSUREs Program.
