Description

The AMSR Level-2A product (AA_L2A) contains brightness temperatures at 6.9 GHz, 10.65 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, 89.0 GHz, 50.3 GHz, and 52.8GHz. Data are resampled to be spatially consistent except for the 50.3GHz and 52.8GHz data, and therefore are available at a variety of resolutions that correspond to the footprint sizes of the observations such as 56 km, 38 km, 24 km, 21 km, 12 km, and 5.4 km, respectively.
