DescriptionThe NASA Scatterometer (NSCAT) Level 3 Mean Wind Fields dataset is produced and distributed by IFREMER/CERSAT. Weekly and monthly mean ocean surface wind vectors, wind stress, wind divergence, and stress curl fields are provided on a global 1x1 degree grid. Standard errors of each parameter are also computed and provided as complimentary gridded fields. An objective statistical interpolation is performed to reconstruct gap-filled and averaged synoptic fields from discrete observations over each time period. This dataset is part of the World Ocean Circulation Experiment (WOCE) package.

Name: NASA Scatterometer (NSCAT)
Swath Width: 1600 km
Description: Every two days, under all weather and cloud conditions, NSCAT measured wind speeds and directions over at least 90% of the Earth's ice-free oceans. NSCAT used six antenna beams to scan two wide bands of ocean, one on each side of the instrument's orbital path. NSCAT transmited short pulses of microwave energy to probe ocean surfaces and then measured the reflected or backscattered power. Variations in the magnitude of this backscattered power are caused by changes in small (centimeter-sized), wind-driven waves. Using a method called Doppler processing, the measured backscattered power was separated into cells at specific locations on Earth's surface.
