Abstract
We report on airborne measurements of the cross-polarized (VH) ocean surface normalized radar crosssection (NRCS) at incidence angles between 15° and 40° obtained at C-band in high-wind (> 30 m s−1) conditions. The present observations were taken in Hurricane Patricia on 23 October 2015 and extend the wind speed range of the existing cross-polarization ocean surface NRCS literature [1]–[4]. The NRCS at the smaller incidence angles decrease as wind speed increases, as expected. At the larger incidence angles, saturation of the NRCS is not observed up to at least 70 m s−1. The results have implications for planned and future scatterometers (e.g., MetOp-SG) that aim to increase the maximum observable wind speeds.
