Data Set Metadata
This Level-3 gridded product (AE_SI25) includes brightness temperatures at 6.9 through 89.0 GHz and sea ice concentrations.
Changes to the Version 3 algorithm for these data include:
- Uses Version 3 of the AMSR-E/Aqua L2A Global Swath Spatially-Resampled Brightness Temperatures data as input
- Improved Antarctic land mask: Includes an updated ice shelf definition created by the National Ice Center Science Department in June 2011, and an updated shoreline developed from ENVISAT and RADARSAT imagery from October 2009 to April 2010. Also, this updated version no longer uses the Level-2A land flag and only uses the updated land mask for surface type classification in the southern hemisphere sea ice concentration algorithm.
- Inclusion of ISO lineage metadata
