Daily ocean conditions from microwaves (AMSR-E/Aqua, 0.25 deg)

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

What it measures. Daily ocean conditions including sea surface temperature, near-surface wind speed, water vapor in the air column, and cloud liquid water, all over open ocean.

How it's made. Derived from microwave readings by the AMSR-E instrument on NASA's Aqua satellite and arranged on a quarter-degree global grid as a daily summary.

How & where you'd use it. Supports tracking of ocean and weather conditions and longer-term ocean climate studies.

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.
