摘　　要：中法海洋卫星(China-France Oceanography SATellite,CFOSAT)由中国和法国联合研制,于2018年发射并已在轨运行5年多,星上的载荷包括SWIM(Surface Waves Investigation and Monitoring)波谱仪和扇形波束旋转扫描微波散射计(CFOSAT SCATterometer,CSCAT),提供了全球海面风场和海浪谱的大面积联合遥感观测资料。中法海洋卫星1—4级数据产品包括后向散射系数、沿轨海面风场和海浪谱、全球网格化风场和海浪谱、宽刈幅海浪、极地海冰、多星融合风场和有效波高等,为海洋环境预报、海洋灾害监测、全球气候变化研究等提供了新的数据源。文中具体介绍了中法海洋卫星产品体系以及国内外学者和机构对海风、海浪数据精度的评估结果。The China-France Oceanography SATellite(CFOSAT),jointly developed by China and France and launched in 2018,has been in orbit for more than 5 years.Onboard payloads include Surface Waves Investigation and Monitoring(SWIM)spectrometer and a fan-beam rotary scanning microwave CFOSAT SCATterometer(CSCAT),which provide the simultaneous remote sensing data of global sea surface wind field and wave spectrum.The level 1-4 data products of CFOSAT include backscattering coefficient,along-track wind field/wave spectrum of the sea surface,global gridded wind field/wave spectrum,wide-swatch wave,polar sea ice,multi-satellite fusion wind field/significant wave height,etc.,which provide a new data source for marine environment prediction,marine disaster monitoring and global climate change research.This paper introduces CFOSAT product series,and the quality evaluation results of wind/wave data from global scholars and institutions.
