Data Announcements

The Submarine Arctic Science Program (SCICEX) Science Advisory Committee (SAC) held their annual meeting in Arlington, VA on May 20-21, 2014. SCICEX is a collaboration between the U.S. Navy and the arctic marine research community to create a program to utilize nuclear-powered submarines for the study of the Arctic Ocean with the goal of acquiring data about the sea ice canopy, water properties, and bathymetry.

The Antarctic Glaciological Data Center (AGDC) at NSIDC is pleased to announce the release of MODIS Mosaic of Antarctica 2008-2009 Image Map, consisting of two cloud-free digital image maps that show mean surface morphology and a quantitative measure of optical snow grain size on the Antarctic continent and surrounding islands.

The AMSR-E Science Investigator-led Processing System (SIPS) has updated the following AMSR-E sea ice data sets to Version 3:

NASA IceBridge Accumulation Radar L1B Geolocated Radar Echo Strength Profiles data for 2013 Arctic are now available from NSIDC. See the Accumulation Radar L1B data catalog page for more information.

NASA IceBridge Photon Counting Lidar L1B Subset Geolocated Photon Elevations data for 2011 and 2012 Antarctica are now available from NSIDC. See the Photon Counting Lidar L1B Elevations catalog page for more information.

NSIDC is pleased to announce that the "DMSP SSM/I-SSMIS Pathfinder Daily EASE-Grid Brightness Temperatures" data set has been updated through 31 May 2014 for all projections (North, South and Global). For more information or to access these data, please visit the data set landing page.

NOAA@NSIDC is pleased to announce that the complete archive of the Multisensor Analyzed Sea Ice Extent – Northern Hemisphere (MASIE-NH) data set, that runs from October 2006 through yesterday, is now available via FTP. In cooperation with the National Ice Center (NIC), NOAA@NSIDC publishes the MASIE-NH data product. This has been a rolling archive showing only the most recent four weeks of data. Users wanting a longer view of changes in sea ice were directed to products like the Sea Ice Index.

The Antarctic Glaciological Data Center (AGDC) at NSIDC is pleased to announce the release of a new data set, High-resolution Atmospheric CO2 during 7.4-9.0 ka. This data set provides a new CO2 record from the Siple Dome ice core, Antarctica, that covers 7.4-9.0 ka (thousand years) with 8- to 16-year resolution.

NASA ICESat/GLAS Altimetry Release-34 binary format data for Laser 1A, 1B, 2A, and 2B campaigns are now available for products GLA05, GLA06, and GLA12-15. 

NSIDC has a new Arctic sea ice data set from NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) program: MEaSUREs Arctic Sea Ice Characterization 25 km EASE-Grid 2.0. This data set, derived from passive microwave brightness temperatures, offers users daily Arctic sea ice locations, sea ice age, day of melt onset, and status of melt onset for the years 1979 through 2012. The data are gridded in the 25 km Equal-Area Scalable Earth Grid (EASE-Grid) 2.0 and provided as netCDF files.

NSIDC is pleased to announce that the "DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures" data set has been updated through 31 May 2014. For more information and to access the new data, see the documentation for this data set.

We are pleased to announce that new validation field campaign data from the Soil Moisture Active Passive Validation Experiment 2012 (SMAPVEX12) are available at NSIDC. The new SMAPVEX12 data sets include:
