The Antarctic Glaciological Data Center (AGDC) at NSIDC is pleased to announce the release of Version 1.1 of the MODIS Mosaic of Antarctica 2003-2004 Image Map.

The ability to view data interactively adds convenience to dynamic data analysis. While static graphs and images are informative, interactive tools allow users to view and analyze data on-the-fly. Readers of our Arctic Sea Ice News and Analysis blog enjoy daily updates on sea ice extent, but some wanted to see data from specific days or years that weren’t provided in the static graphs. Behold Charctic.

NOAA@NSIDC is pleased to announce the release of the ClimoBase: Rouse Canadian Surface Observations of Weather, Climate, and Hydrological Variables, 1984-1998 data set. ClimoBase is a collection of surface-climate measurements taken in Northern Canada by Dr. Wayne Rouse between 1984 and 1998 in three locations: Churchill, Manitoba; Marantz Lake, Manitoba; and Inuvik, Northwest Territories. These data are comprised of 177 different variables including solar time, wind speed, wind direction, dry-bulb, wet-bulb, and vapor pressure at 24 sites.

NASA ICESat/GLAS Altimetry Release-34 binary format data for Laser 3E, 3F, and 3G campaigns are now available for products GLA05, GLA06, and GLA12-15. 

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.

NASA Aquarius level-3 weekly polar-gridded Normalized Radar Cross Section, Sea Surface Salinity, and Brightness Temperature data products are now available from NSIDC. For documentation, and to access the data, see the Aquarius L3 NRCS, Aquarius L3 SSS, and Aquarius L3 TB data set landing pages.

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 Canadian Meteorological Centre (CMC) Daily Snow Depth Analysis data set has been updated with new data for 2012. This data set now also includes daily and monthly analysis data for 01 August 1998 through 31 December 2012 and climatology data for 01 August 1998 to 31 December 2011. For complete details and documentation and to access these data, visit the Canadian Meteorological Centre (CMC) Daily Snow Depth Analysis Data Web page.

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.
