风云三号气象卫星是实现全球、全天候、多光谱、三维、定量遥感的我国第二代极轨气象卫星系列，已成为世界气象组织在亚洲的重要业务卫星，为提高我国气象卫星在世界气象组织卫星观测系统中的地位奠定了重要的基础，世界气象组织已将风云三号气象卫星纳入世界气象卫星全球观测业务序列。依靠我国自主力量设计与建设的新一代极轨气象卫星风云三号地面应用系统首次利用海内外接收站网实现了上、下午星全球资料的高时效获取，首次利用国产卫星实现了大气三维探测，实现了臭氧和辐射收支等探测的高精度处理，突破了卫星资料定量反演、数值预报同化应用以及气候应用等核心技术。

FY-3 is the second generation of Chinese poplar orbiting meteorological satellite with the capability of multi-spectral, three-dimensional and quantitatively global observation. As one of the most important space observation component of World Meteorological Organization, FY-3 satellites are playing key role in weather forecast, climate analysis, environmental management, disaster monitoring etc. The FY-3 ground segment has the capacity of global data acquisition in short latency. After data pre-processing and product generation, FY-3 data and products provide comprehensive service in the field of atmospheric sounding, ozone and radiation budget monitoring, data assimilation, climate application.
