From 9:00 a.m. to noon (USA Mountain Time) Wednesday October 5, AMSR-E, Aquarius, IceBridge, ICESat/GLAS, MODIS, NISE, and SMAP data will not be available for ordering due to system maintenance.
NOTE: Reverb will be decommissioned in the coming months and replaced with Earthdata Search. All links to Reverb will be removed at that time.
AMSR-E/Aqua Daily L3 6.25 km 89 GHz Brightness Temperature Polar Grids, Version 3
This Level-3 gridded product (AE_SI6) includes brightness temperatures at 89.0 GHz. Data are mapped to a polar stereographic grid at 6.25 km spatial resolution. This product is an intermediate product during processing of AMSR-E Level-3 sea ice products at 12.5 km and 25 km resolution.
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
