The AMSR-E/AMSR2 Unified L3 Daily 25 km Brightness Temperatures & Sea Ice Concentration Polar Grid Version 1 data set available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has been reprocessed to correct an issue with the parameter designation (indexing) with the brightness temperature values in the B01 product. The file names for the data set have changed to reflect this update and are now designated with a B02 Product Maturity Code. This data set provides sea ice concentration derived from brightness temperatures using the NASA Team 2 (NT2) algorithm for the Northern and Southern Hemisphere from 02 July 2012 to present and includes: six daily brightness temperature fields for channels ranging from 6.9 through 89.0 GHz, three daily sea ice concentration fields, three daily sea ice concentration difference fields for ascending/descending orbits, and full orbit daily averages.
