This website hosts information pertaining to four Earth-orbiting missions, both current and past. Each mission was tasked to measure ocean winds from space using scatterometry. A scatterometer is a microwave radar sensor which measures the reflection (or scattering effect) produced while scanning the surface of the Earth from an aircraft or a satellite. (Go to Scatterometry to learn more about scatterometers.) By measuring global sea-surface wind speed and direction, ocean scatterometer data can help meteorologists more accurately predict the marine phenomena that affect human life on a daily basis.
