AMSR-E/Aqua Daily L3 12.5 km Brightness Temperature, Sea Ice Concentration, & Snow Depth Polar Grids, Version 4

This data set (AE_SI12) reports average daily, 12.5 km resolution, horizontally and vertically polarized brightness temperatures (Tb) at four frequencies—18.7 GHz, 23.8 GHz, 36.5 GHz and 89.0 GHz. It also reports: daily sea ice concentrations derived with the Enhanced NASA Team (NT2) algorithm, daily sea ice concentration differences between NT2 and the legacy AMSR Basic Bootstrap Algorithm (BBA), and daily snow depths over sea ice. Data are provided on Northern and Southern Hemisphere, polar stereographic grids.

These data are derived from observations acquired by the Advanced Microwave Scanning Radiometer for EOS (AMSR-E).
