Heat and moisture moving between sea and air (daily)

Goddard Satellite-Based Surface Turbulent Fluxes, 0.25 x 0.25 deg, Daily Grid F14 V3 (GSSTF_F14) at GES DISC
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. This estimates how much heat and moisture move between the ocean surface and the air above it each day, mapped across the globe. These exchanges drive evaporation and how the ocean warms or cools the atmosphere.

How it's made. It is built from microwave readings by the SSM/I instrument on the DMSP F14 satellite, processed daily and projected onto a worldwide quarter-degree grid.

How & where you'd use it. It serves mostly as an input to a combined multi-satellite product. Climate and ocean researchers use these fluxes to study how the sea and atmosphere trade energy and water.

Official description

These data are part of the Goddard Satellite-based Surface Turbulent Fluxes Version 3 (GSSTF3) Dataset recently produced through a MEaSURES funded project led by Dr. Chung-Lin Shie (UMBC/GEST, NASA/GSFC), converted to HDF-EOS5 format. The stewardship of this HDF-EOS5 dataset is part of the MEaSUREs project. This is a Daily (24-hour) product; data are projected to equidistant Grid that covers the globe at 0.25x0.25 degree cell size, resulting in data arrays of 1440x720 size. The daily fluxes are produced for each individual available SSM/I satellite tapes (e.g., F11, F13, F14 and F15), and then serve as input to the Combined daily fluxes (GSSTF_3). The short name of this data set is GSSTF_F14.
