The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has added SMMR data to the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 1 data set.

Also, the F10 data from this 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.

NSIDC DAAC would like to announce a change to data access for the MEaSUREs Multi-year Greenland Ice Sheet Velocity Mosaic, Version 1 data set. Data access is now solely available through our primary archive at: https://n5eil01u.ecs.nsidc.org/MEASURES/NSIDC-0670.001/.

The MEaSUREs Greenland Annual Ice Sheet Velocity Mosaics from SAR and Landsat, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).

NASA SnowEx17 SnowMicroPen (SMP) Raw Penetration Force Profiles data are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains raw penetration force profiles measured at snow pits and along linear transects at Grand Mesa, Colorado using the SMP, a digital snow penetrometer.

Data Set DOI: https://doi.org/10.5067/ZPOLBRHVWG5V

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.

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 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.

The NASA IceBridge MCoRDS L1B Geolocated Radar Echo Strength Profiles, Version 2 data set now includes data for the 2016 Antarctica campaign.
