Abstract

Accurate observations of high winds over the oceans are important for analyses of phenomena that range from regional (tropical and extratropical storms) to global scales (air-sea exchanges, ocean circulation). However, so far a lack of in-situ observations of winds above 20 m/s posed severe limitations to the accuracy of satellite-retrieved high winds as insufficient data were available for training and validation of wind speed retrieval algorithms. An additional difficulty is the fact that many high wind observations are contaminated by rain. This leads to a strong degradation in the accuracy of wind speed measurements by active sensors (scatterometers) and a complete breakdown of the wind speed retrieval by passive sensors (radiometers) if the standard algorithms, which have been trained in rain-free conditions, are used. © 2011 IEEE.
