Worldview: This application allows you to interactively browse global satellite imagery within hours of it being acquired. You can also save it, share it, and download the underlying data.
Earthdata Search: NASA's newest search and order tool for subsetting, reprojecting, and reformatting data.
Reverb: NASA search and order tool for subsetting, reprojecting, and reformatting data.

NOTE: Reverb will be decommissioned in the coming months and replaced with Earthdata Search. All links to Reverb will be removed at that time.

AE_SI6

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.

Version Summary:

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

FAQ

How do I extract latitude and longitude information from AMSR-E sea ice data?

AMSR-E sea ice data sets are provided in the Polar Stereographic projection. NSIDC provides gridded latitude and longitude files that give the coordinates for the center of each grid cell. The latitude and longitude files are... read more
