Abstract

Wind fields under hurricane conditions are retrieved from C-band SAR data acquired by the Canadian satellite RADARSAT-1. Therefore, an algorithm is utilized, which has shown to give very good results under low and moderate wind conditions. The algorithm extracts wind directions from wind induced streaks imaged by the SAR, which are very well aligned with the mean surface wind direction. Wind speeds are extracted from the SAR measured normalized radar cross section utilizing a scatterometer C-band model, which describes the dependency of the NRCS on wind speed, wind direction and incidence angle. The SAR-retrieved wind fields are compared to results of a high resolution numerical tropical cyclone model. Furthermore, the SAR-retrieved wind fields are used to quantitatively measure the dimension and location of the hurricane eye.
