Description

This data set reports 6.25 km resolution, horizontally and vertically polarized average daily 89.0 GHz brightness temperatures for the Advanced Microwave Scanning Radiometer (AMSR) for EOS (AMSR-E) and AMSR2 instruments. The data are provided on north and south polar stereographic grids.

The brightness temperatures are derived from Level 1R data that has been spatially resampled by the Japan Aerospace Exploration Agency (JAXA) to unify AMSR-E and AMSR2 observations.
