The AMSR-E/AMSR2 Unified L3 Daily 6.25 km Polar Gridded 89 GHz Brightness Temperatures, Version 1 data set available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has been updated to reflect a new version. The data file names are now designated with a B02 Product Maturity Code. Since all the AMSR-E/2 Unified sea ice products are produced by the same software, this version was generated as a result of reprocessing of the AMSR-E/AMSR2 Unified L3 Daily 25 km Brightness Temperatures & Sea Ice Concentration Polar Grid, Version 1 data set to B02 to correct an error. There are no changes to the 6.25 km data in the B02 version. Only the file name has changed to reflect the new version.
