Weekly ocean conditions from a microwave satellite (AMSR-E on Aqua)

AMSR-E/Aqua Weekly L3 Global Ascending/Descending .25x.25 deg Ocean Grids V002
atmosphere NASA NSIDC_CPRD Level 3 HDF-EOS2
In plain English

What it measures. Weekly snapshots of ocean conditions worldwide: sea surface temperature, near-surface wind speed, water vapor in the air column, and cloud liquid water, all on a fine grid.

How it's made. Derived from the AMSR-E microwave instrument on NASA's Aqua satellite and averaged into weekly global maps.

How & where you'd use it. Useful for tracking ocean and weather conditions and for studies of how the ocean and atmosphere interact over time.

Official description

The Level-3 daily product (AE_DyOcn), weekly product (AE_WkOcn), and monthly product (AE_MoOcn) include SST, near-surface wind speed, columnar water vapor, and columnar cloud liquid water over oceans in a 0.25 degree by 0.25 degree grid, generated from AE_Ocean.
