Early validation of operational SAR wind retrievals from Sentinel-1A [PDF]
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015 The computation of wind speeds at high (< 1 km) resolution from spaceborne synthetic aperture radar (SAR) is a mature geophysical application. A number of researchers, a modest sample of which are cited [1, 2, 3, 4, 5, 6, 7], have described the geophysical relationship between normalized radar cross section (NRCS) and ocean surface wind speed, and how ...
