Ku-band Radar Altimeter Surface Wind Speed Algorithm
An algorithm for the retrieval of surface wind speed from Ku-band altimeter backscatter coefficient is proposed. The algorithm was derived using two-month worth of ENVISAT altimeter backscatter data collocated with ECMWF model and buoy wind speeds. The algorithm was extensively verified for ENVISAT, ERS2 and Jason-1 altimeters. The algorithm performance is better than the “modified Chelton-Went...
متن کاملKu-Band Sea Surface Radar Backscatter at Low Incidence Angles under Extreme Wind Conditions
This paper reports Ku-band normalized radar cross section (NRCS) at low incidence angles ranging from 0◦ to 18◦ and in the wind speed range from 6 to 70 m/s. The precipitation radar onboard the tropical rainfall measuring mission and Jason-1 and 2 have provided 152 hurricanes observations between 2008 and 2013 that were collocated with stepped-frequency microwave radiometer measurements. It is ...
متن کاملThe Research on Ocean Surface Wind Speed Retrieval by Neural Network Algorithm for HY2 Altimeter
The neural network algorithm in this paper is applied to the ocean surface wind speed retrievals. Firstly, the Ku band backscattering coefficient (σKu) is considered as the input parameter to retrieve the wind speed and the retrieval precision reaches 1 m/s (root mean square error) for HY2 altimeter. Secondly, by introducing the Ku-band significant wave height (swhku), C-band backscattering coe...
متن کاملAn Estimate of the Geosat Altimeter Wind Speed Algorithm at High Wind Speeds
Existing wind speed algorithms for satellite altimeters have been developed from data in the range 0 to 20 m/s. At higher wind speeds the available algorithms diverge alarmingly. By comparing Geosat altimeter values of the radar cross section with model predictions of the surface winds during satellite overpasses of tropical cyclones, a wind speed algorithm valid for wind speeds between 20 and ...
متن کاملA Model for Wind Speed and Wave Height Retrieval from Radar Altimeter Measurements
A numerical algorithm is here proposed to simulate the measurement of ocean wave height and wind speed by radar altimeter. The algorithm takes into account a realistic ocean wave spectrum and employs a parametric sub-model to simulate the electromagnetic waves scattering from the surface, thus providing greater flexibility and realism than the analytical models currently used. The model is show...
