We give a review of surface wind-speed retrieval algorithms using satellite radio-altimeter data and analyze the efficiency of these algorithms. The data processing by new radio altimeters (JASON and ENVISAT) showed that the two-parameter algorithm developed for the satellite "Topex A" effectively operates with the data of the new radio altimeters and exceeds in accuracy the conventional algorithm by 5-10%. We discuss two main reasons for the wind-speed retrieval errors: (i) ambiguous relationship between the wind speed and the backscattering cross section and (ii) regional features of the wave climate formation. Within the framework of a two-parameter algorithm, we propose a new approach for the wind-speed retrieval problem, in which two-mode structures (wind waves and a swell) are taken into account. The data processing confirmed that the new approach allows one to reduce the error related to regional features of the wave climate formation by another 5-7%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
