Data Updates
NSIDC has been notified of an error in AMSR-E sea ice data products that caused valid data in the Southern Hemisphere to be obscured by a land mask. The products and algorithms affected by this error are:
pdates are complete for following AMSR-E data products:
- AMSR-E/AQUA Daily L3 6.25 km 89GHz Brightness Temperature Polar Grids
- AMSR-E/Aqua Daily L3 12.5 km Tb, Sea Ice Concentration, and Snow Depth Polar Grids
- AMSR-E/AQUA Daily L3 25 km Tb, Sea Ice Temperature, & Sea Ice Conc. Polar Grids
Algorithm updated to: Validated 14 – Stage 1
The Japan Aerospace Exploration Agency (JAXA) has completed reprocessing of the AMSR-E/Aqua L1A Raw Observation Counts data set to Version 3. These Version 3 data are now available from the beginning of the AMSR-E mission through 04 October 2011, when the AMSR-E sensor stopped operating. The new version includes improved geometric accuracy and a switch to a new HDF version, from 4.2r1 to 4.2r4.
NASA IceBridge LVIS L0 Raw Ranges data for 2012 Greenland are now available from NSIDC. See the IceBridge LVIS L0 Raw Ranges Web page at https://nsidc.org/data/ilvis0 for more information.
NSIDC has published an update to the NASA MEaSUREs program data set MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from InSAR, supplying data for additional locations in Greenland. The data were produced from TerraSAR-X (TSX) image pairs collected from January to May 2009.

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.
