QuikSCAT
STATUS
Operational
AVAILABILITY
Data available through the NASA JPL PO.DAAC web site at http://podaac.jpl.nasa.gov/ PO.DAAC distributes data from several instruments that measure ocean vector winds. Chief among these are the SeaWinds instruments (Ku-band microwave radar scatterometers on board the ADEOS-II and the QuikSCAT satellites) and their predecessor NSCAT. Both swathed and globally gridded data, as produced by the JPL Scatterometry Project, are publicly available. PO.DAAC also distributes data created from the Project data, e.g. wind-stress products (generated at PO.DAAC) and sigma0 products.

Satellite Instruments
QuikSCAT mission is intended to record sea-surface wind speed and direction data under all weather and cloud conditions over Earth's oceans. SeaWinds is the main instrument on the QuikSCAT satellite. SeaWinds is an active radar scatterometer. This scatterometer operates by transmitting high-frequency microwave pulses to the ocean surface and measuring the echoed radar pulses bounced back to the satellite. The scatterometer estimates wind speed and direction over the Earth's oceans at 10 m above the surface of the water.
