THE CEOS DATABASE : Missions, Instruments and Measurements
CEOS EO HANDBOOK – INSTRUMENT SUMMARY - SeaWinds -
Full Name SeaWinds Status Operational
Instrument Agencies NASA Maturity
Instrument Type Scatterometers Geometry Conical scanning
Instrument Technology Radar scatterometer Sampling Imaging
Data Access Open Access Data Format
Measurements and Applications Measurement of surface wind speed and direction. The SeaWinds antenna on QuikSCAT stopped rotating in November 2009, and the instrument no longer collects ocean wind vector data. However it still provides calibration data for other on-orbit scatterometers, which enables the continuation of a climate-quality wind vector dataset.
