Coriolis is an Air Force Space Test Program and Space Naval Warfare Systems Command meteorological science mission to demonstrate the viability of using polarimetric radiometry to measure ocean surface wind speed and direction from space, and to demonstrate predictions of geomagnetic disturbance through continuous observation of Coronal Mass Ejections (CME).
Coriolis carries two instruments: WindSat and the Solar Mass Ejection Imager (SMEI). WindSat is a receiver which measures ocean surface wind speed and direction. The WindSat instrument provides risk reduction experience for the development of the Conical Microwave Imager Sounder (CMIS). The SMEI instrument is an all-sky camera experiment for imaging CMEs propagating from the sun through the solar wind.
Key performance features achieved by the Coriolis satellite include extremely low levels of EMI to facilitate operation of Windsat's passive radiometers, and the physical accommodation of Windsat's high (3.3 meter) profile with its spinning top reflector.
