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.
MEaSUREs Annual Greenland Outlet Glacier Terminus Positions from SAR Mosaics, Version 1 data set is now available at version 1.1. The minor changes in this version include: Added data for winters of 2014/2015, 2015/16, 2016/17 Added new parameter attributes for the new data Added 29 new glaciers Provided a new GlacierID file with added glaciers and updated attributes
This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
NASA IceBridge-related CryoSat-2 Level 4 Sea Ice Elevation, Freeboard, and Thickness data are now published at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains 30-day averaged Arctic sea ice thickness estimates, with freeboard and ice surface roughness, derived from from the ESA CryoSat-2 Synthetic Aperture Interferometric Radar Altimeter (SIRAL)

A new data set, Daily Snow Depths and SWE from GPS Signal-to-Noise Ratios, is now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The data comprise daily snow depth and snow water equivalent (SWE) at 223 stations located primarily in the western United States, including Alaska.
On 1 September 2017, the NSIDC Data Viewer tool at ftp://sidads.colorado.edu/pub/tools/dataviewer/ will be decommissioned; thus, permanently unavailable for any future use. There are no plans to replace it at this time.

The F11 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 MEaSUREs Greenland Image Mosaics from Sentinel-1A and -1B, Version 2 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated with mosaics through 30 June 2017. This data set, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides 6- and 12-day 50 m resolution image mosaics of the Greenland coastline and ice sheet periphery.
The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) decommisioned the Binary Data Subsetter on 01 August 2017. Access to all ICESat/GLAS binary data products at the NSIDC DAAC was removed on 01 August 2017. ICESat/GLAS data remain available in HDF5 format.
NASA IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies data for 2016 Antarctica are now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Additionally, on July 26, 2017, the entire IceBridge IGGRV1B data set was replaced with re-leveled data to ensure consistency within the entire data set. This data set contains Greenland and Antarctica gravity measurements taken from the Sander Geophysics AIRGrav airborne gravity system.
The MEaSUREs Greenland Monthly Image Mosaics from MODIS, 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, part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides monthly image mosaics of the Greenland coastline and ice sheet periphery. The image mosaics are constructed from composited MODIS imagery, acquired each month between March 2008 to September 2016.
The MEaSUREs Greenland Image Mosaics from Sentinel-1A and 1B, Version 2 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The changes for Version 2 include:
The F08 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.
