AMSR-E/AMSR2 Unified L3 Global Daily 25 km EASE-Grid Snow Water Equivalent, Version 1

This AMSR-E/AMSR2 Unified Level-3 data set provides daily estimates of snow water equivalent (SWE) at 25 km resolution, derived from brightness temperature measurements acquired by the Advanced Microwave Scanning Radiometer (AMSR) for EOS (AMSR-E) and AMSR2 instruments. SWE data are provided on the azimuthal 25 km Equal-Area Scalable Earth Grid (EASE-Grid) for both the Northern and Southern Hemisphere.

The data were generated from input brightness temperatures which were resampled by the Japan Aerospace Exploration Agency (JAXA) to intercalibrate, or unify, the AMSR-E and AMSR2 missions.
