中文摘要:
      风云四号是中国新一代静止轨道气象系列卫星,该系列卫星的设计目的是满足中国气象局2020年前后的业务应用和服务需求。风云四号系列的首发星为科研试验星,代号FY-4A,已于2016年12月14日在西昌卫星发射中心成功发射,从FY-4B开始,风云四号系列卫星将提供业务服务。成像仪是风云四号系列卫星的核心载荷之一,其成像性能比目前使用的风云二号系列卫星在时间空间分辨率、光谱通道等方面有显著提升。本文将就该仪器的工作特点、观测模式设置、光谱通道的选取和特点进行介绍,由于FY-4A卫星正在进行为期一年的在轨测试,本文还将展示在轨测试图像。
英文摘要:
      Fengyun 4A(FY-4A), the R&D mission for Chinese second-generation geostationary meteorological satellite series was successfully launched at 00:11 BST on December 14,2016 at Xichang Satellite Launch Center, southwest China's Sichuan Province. From FY-4B, Chinese second-generation geostationary meteorological will be operational. To satisfy CMA weather forecast and service requirement toward 2020, the Advanced Geosynchronous Radiation Imager (AGRI) is one of the most important payload onboard the Chinese second-generation geostationary meteorological satellite. The AGRI will provide a significant advancement over the current FY-2 VISSR such as more spectral channels, faster imaging and higher spatial resolution. In this paper, the FY-4 working mode, channel setting and potential application are discussed. As FY-4A is under one year post launch test, which will end by December 2017, some test images of FY-4A are presented.
