Description

The AMSR-E/AMSR2 Unified L3 Global Weekly Ascending/Descending .25 x .25 deg Ocean Grids data set (AU_WkOcn) reports weekly estimates of water vapor, cloud liquid water content, and surface wind speed over the ocean on a global 0.25° × 0.25° resolution grid. The data are derived from the AMSR-E/AMSR2 Unified L2B Global Swath Ocean Products, Version 1 data set.

Sea surface temperatures from the NOAA 1/4° Daily Optimum Interpolation Sea Surface Temperature (OISST) product are also included.
