Data Announcements

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is pleased to announce a new data set, the MEaSUREs MODIS Mosaic of Greenland 2005 (MOG2005) Image Map. This data set consists of two digital image maps for Greenland that show surface morphology and snow grain size. The image maps are constructed from MODIS imagery acquired during 2005 and provide nearly cloud-free views of all land areas and islands larger than a few hundred meters, including the ice caps on Baffin Island, Devon Island, Axel Heiberg Island, and Ellesmere Island.

The Greenland Ice Mapping Project (GIMP) Digital Elevation Model is now available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set, funded by NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, consists of an enhanced resolution digital elevation model (DEM) for the Greenland Ice Sheet.

The 4 km Daily Sea Ice Concentration Product, MASAM2, has had all data gaps filled. It is a now a continuous, daily time series from 02 July 2012 to the present. MASAM2 is updated daily with a 2-day lag time. For more information or to access this data set, see the MASAM2: Daily 4 km Arctic Sea Ice Concentration product page.

The AMSR-E Science Investigator-led Processing System (SIPS) has updated the AMSR-E L2B rain data set, AMSR-E/Aqua L2B Global Swath Surface Precipitation GSFC Profiling Algorithm, to Version 3.

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is pleased to announce that Version 6 (Collection 6) reprocessing is complete for our MODIS sea ice data sets. Forward–processing will continue for both Version 5 and Version 6 for approximately one year, after which Version 5 forward-processing will be discontinued. To obtain MODIS Version 6 sea ice data, visit the MODIS collection. Questions? Contact NSIDC's User Services Office.

We are pleased to announce that all data from the NASA Soil Moisture Active Passive (SMAP) mission are now available at the National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) and the NASA Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC). The two NASA DAACs jointly manage SMAP science data on behalf of the NASA ESDIS Project. SMAP combines coincident L-band radar and radiometer measurements to produce global, high-resolution soil moisture and freeze/thaw estimates.

NOAA@NSIDC is pleased to announce that the online search interface for the Dehn Arctic Sea Ice Charts database has been updated. Improvements include the ability to define your search by region and time period at the same time, the search results now list how many images were returned, and a "Select/Deselect All" button has been added to the ordering page for ease in selecting images.

NOAA@NSIDC is pleased to announce the release of a 1 km gridded MASIE sea ice product in addition to the 4 km version. The Multisensor Analyzed Sea Ice Extent (MASIE) helps to give the best available Arctic-wide answer to the question: Where is Arctic sea ice now? MASIE products provide measurements of daily sea ice coverage for the Northern Hemisphere and 16 Arctic regions in a polar stereographic projection in 4 km grid cells and now in 1 km grid cells as well. In addition, a full Northern Hemisphere time series graph has been added to the MASIE Time Series Plots.

The Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), is pleased to announce the release of a new data set. MEaSUREs Annual Greenland Outlet Glacier Terminus Positions from SAR Mosaics provides glacier terminus positions in individual shapefiles for winter 2000–2001, annually during winters 2005–2006 to 2008–2009, and winter 2012–2013.
