DescriptionThis dataset contains images of daily averaged ocean surface wind vectors derived from the gridded Level 3 QuikSCAT ocean surface wind vector dataset. These images are provided in GIF format at 900x600 pixel resolution. Vector arrows are colored according to wind speed, and a color bar is available to estimate the wind speed. The arrow is directionally oriented with the flow direction of the 10 m ocean surface wind velocity retrievals derived from the NASA SeaWinds scatterometer aboard the QuikSCAT satellite platform.

Disclaimer: this dataset is meant for quick-look purposes only and is not intended for science-quality research applications.

Name: SeaWinds Scatterometer (SEAWINDS)
Swath Width: 1800 km
Description: SeaWinds is a Ku-band (13.4 GHz) Scatterometer which features a single circular scanning dish antenna to provide pencil-beam measurements, as opposed to the common fan beam design as seen with other spaceborne scatterometers. The pencil-beam design has several key advantages over the more common fan beam design: higher signal-to-noise ratio, smaller size, and superior coverage. The SeaWinds single antenna utilizes twin offset feeds, thus providing two pencil-beam footprint paths with an elliptical sampling footprint of approximately 25 km (in azimuth) by 37 km (in look/range direction); these pencil beams have opposing polarizations (i.e., vertical and horizontal), thus achieving dual-polarization. The SeaWinds instrument provides a full 1800 km-wide swath coverage (including the nadir region), which allows for a nominal daily measurement coverage of 90% over the ice-free oceans.
