- Adjusted tie points to be consistent with the AMSR-E Bootstrap algorithm
- Adjusted Southern Hemisphere land mask to account for changes in extent and positions of ice shelves
- Reprocessed entire SMMR-SSM/I time series
Important: Because Version 2 is inter-calibrated with AMSR-E, it is not compatible with Version 1 of this data set. Users should acquire the entire Version 2 data set in order to update their time series. For further information on Version 2 data processing, see Enhanced Sea Ice Concentrations from Passive Microwave Data.
