Quick Scatterometer (QuikSCAT)
Status:
Completed
Mission Category:
Earth Observing System (EOS)
Launch Date: June 19, 1999
Launch Location: Vandenberg Air Force Base, CA
Designed Life: June 19, 2002
Actual Completion Date: November 23, 2009
The Quick Scatterometer (QuikSCAT) acquired accurate, high-resolution, continuous, all-weather measurements of global (land, ice, and ocean) radar cross-sections and near-surface vector winds over the ice-free global oceans. The wind measurements are used for research investigations as well as in operational weather prediction. Radar cross-sections from land and ice-covered regions are used for vegetation classification/monitoring, cryospheric investigations, and operational ice-edge and iceberg detection and monitoring.
Antenna ceased rotating in November 2009: still providing useful data through cross-calibration with other satellites.
