我國成功發射風雲四號氣象衛星
China successfully launched the Fengyun-4 satellite last Sunday from the Xichang Satellite Launch Center in Sichuan, marking an upgrade for China's meteorological satellites in geostationary orbit. The satellite was taken into orbit by the Long March-3B carrier rocket.
上週日，我國在四川西昌衛星發射中心用長征三號乙運載火箭成功將風雲四號衛星送入軌道，這標誌着我國靜止軌道氣象衛星的升級換代。The Fengyun-4 satellite, the first of China's second-generation weather satellites in geostationary orbit to be launched, is also the country's first quantitative remote-sensing satellite in high orbit.
風雲四號衛星是我國第二代靜止軌道氣象衛星的首發星，也是我國首顆高軌道定量遙感衛星。The satellite will make high time, spatial and spectral resolution observations of the atmosphere, clouds and space environment of China and surrounding regions, significantly improving capabilities of weather and climate forecasts, according to the State Administration of Science, Technology and Industry for National Defense.
據國家國防科技工業局介紹，風雲四號衛星將對我國及周邊地區的大氣、雲層和空間環境進行高時間分辨率、高空間分辨率、高光譜分辨率的觀測，大幅提高天氣預報和氣候預測能力。
The China Meteorological Administration is the primary user of the satellite.
風雲四號衛星的主用戶爲中國氣象局。Fengyun-4 innovatively achieves integrated payload configuration. Such elaborated designation can multiply the function of Fengyun-4 while substantially cutting down on the research and development costs.
風雲4號衛星創新性地實現了集成的有效載荷配置。這樣精心的設計可以成倍的提升風雲4號的功能，同時還可以大幅削減研發成本。Traditionally the imager and sounder are carried by different satellites to prevent mutual interference. However, Fengyun-4 successfully overcame this tough problem in the world and various instruments onboard can peacefully work on the same platform without upsetting each other.
傳統的圖像和聲音信號都是由不同的衛星來運載的，以此來防止相互干擾。不過，風雲4號衛星成功地克服了這個世界性的棘手問題，各種儀表板可以在同一平臺上正常運行，而且不會互相干擾。"What's more, it realizes comprehensive observations of atmosphere with various means for the first time in the world." Yu Xinwen, Deputy Administrator of China Meteorological Administration (CMA) and commander-in-chief of FY-4 satellite program said.
中國氣象局副局長、風雲4號衛星項目的總負責人於新文表示：“更重要的是，該衛星在世界上首次實現了對大氣的多手段綜合觀測。”
