AMSR-E/Aqua Daily L3 25 km Brightness Temperature & Sea Ice Concentration Polar Grids V004
Listed in NASA Earthdata CMR
Description
This data set (AE_SI25) reports average daily, 25 km resolution, horizontally and vertically polarized brightness temperatures (Tb) at six frequencies—6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, and 89.0 GHz—plus sea ice concentrations and sea ice concentration differences between the Enhanced NASA Team (NT2) algorithm and the legacy AMSR Basic Bootstrap Algorithm (BBA). 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) on board the NASA Aqua satellite.
