Wind Retrieval using Marine Radars
Abstract
Within the High Resolution Air-Sea Interaction (HiRes) DRI the Center for Maritime Research and Experimentation (CMRE), former NATO Undersea Research Center, will develop and validate methodologies to retrieve wind field parameters from X-band marine radars. The main parameters are the mean surface wind vector; the high-resolution wind field, as well as wind gusts in vicinity of the measurement platform (within 2000 m). In contrast to traditional wind measurements marine radar retrieved winds are not influenced by the blockage and shadowing of the platform itself. Therefore, marine radars are expected to be an ideal solution to measure winds operationally from large platforms and ships. As the wind information is an important parameter in the marine radar wave measurement and the wave modeling, we anticipate that our radar retrieved wind information will help to improve the measuring and modeling activities of phase-resolved surface wave fields undertaken within HiRes. The scientific objective is to develop a methodology to retrieve surface wind speed and direction using marine radar data acquired near grazing incidence at X-band with horizontal polarization in transmit and receive. In particular we aim at developing an algorithm that requires as little as possible calibration and straightforward calibration procedures. A further objective is to develop a methodology to detect and quantify wind gusts with marine radar imagery within 2 to 4 km of the platform, which aims toward a short time forecast of wind gusts/variability at the measurement platform. The validation as well as limitation of the developed methodologies will be investigated utilizing the measurements obtained during the HiRes experiment in June 2010 from RV Flip and RV Sproul.
