Abstract:The China-France Oceanography SATellite (CFOSAT ) firstly makes joint observations of ocean surface wind vector and wave spectrum in the world. The CFOSAT SCATterometer (CSCAT) onboard adopts a new observation scheme of Ku-band fan-beam rotary scanning system, and can measure more incidence angles of the same wind vector cell and obtain more observation samples in contrast with the pencil-beam rotary scanning system. So, CSCAT could improve the wind product precision. Based on the summary of the work related to the operational-oriented validation of CSCAT and the satellite management department’s understanding of the validation system for satellite remote sensing products, a validation technology system for CSCAT wind products is presented in terms of CSCAT’s loading characteristics. The system, including operational-oriented evaluation and scientific-oriented evaluation, is jointly implemented by the satellite management department, data users, and scientific researchers, which helps improving the quality of satellite remote sensing products and the development of observation and validation technologies. Also, the operational-oriented technology system is helpful to comprehensively and systematically evaluate and monitor the measurement performance of CSCAT, and could support for optimizing the instrument’s performance and improving the wind retrieval algorithm. At the same time, the validation technology system can also help CSCAT product users to more comprehensively understand the accuracy characteristics of wind field products and promote the quantitative application of CSCAT wind field products.
