NSIDC is pleased to announce the release of two Antarctic data sets, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program. The MEaSUREs program aims to develop consistent global and continent scale data records related to earth science, or Earth System Data Records (ESDRs).

12,500 Browse Images from 19 June 2002 to 10 September 2002 are unavailable for MODIS/Terra Snow Cover 5-Min L2 Swath 500m (MOD10_L2) and MODIS/Terra Sea Ice Extent 5-Min L2 Swath 1km (MOD29).

As of 06:58 UTC on 04 October 2011, the AMSR-E instrument on board the Aqua satellite stopped producing data due to a problem with the rotation of its antenna.

On 28 September 2011, Version 3 (V003) of the AMSR-E/Aqua L1A Raw Observation Counts data set was released by the Japan Aerospace Exploration Agency (JAXA).

A new data set is available at NSIDC, the Enhanced-Resolution SSM/I and AMSR-E Daily Polar Brightness Temperatures.

Updated EASE-Grid SSM/I-SSMIS data are now available at NSIDC.

NSIDC has released a new sea ice data set, the AMSR-E/Aqua Daily L3 6.25 km Sea Ice Drift Polar Grids.
