NOAA@NSIDC plans to change the baseline climatological period for the Sea Ice Index and the Arctic Sea Ice News and Analysis (ASINA) from 22 years (1979-2000, inclusive) to 30 years (1981-2010, inclusive) this July.
New data regarding snow, sea ice, Greenland surface melt and more will be coming soon to NSIDC. The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program is dedicated to the development of consistent global and continental scale data records related to earth science. NSIDC currently archives six data sets from the MEaSUREs program, and the additional data sets will be available in the near future.
Updated Version 3 brightness temperature data are now available for the AMSR-E/Aqua Level-2A Global Swath Spatially-Resampled Brightness Temperatures (AE_L2A) data set. Changes to the Version 3 algorithm for these data include:
This data set contains temperature-depth profile measurements taken in 22 boreholes drilled on the West Antarctic Ice Sheet, which exhibit two distinctly different thermal states of basal ice: a warm state and a relatively colder state.

The NASA IceBridge Project is comprised of airborne data over the most dynamic areas of the Arctic, Greenland, Alaska and Antarctica. The data gathered by this project are unique in that they are spatially referenced by flight lines, flights are flown during approximately 3-month campaigns, and data are collected by a wide variety of instrumentation.
The NASA IceBridge Data Portal provides a single location from which one can get an overview of all the IceBridge data sets.

ELOKA is pleased to announce the release of the Local Observations from the Seasonal Ice Zone Observing Network data set. This data set contains observations of sea ice, weather, and wildlife collected by Indigenous Inupiaq and Yup'ik sea ice experts in several communities along the northern and western coasts of Alaska, beginning in 2006. The product is a database of local observations spatially referenced as near or around Alaskan villages and is available via a Web interface.
