中文摘要:
      风云三号D气象卫星搭载10个载荷:中分辨率光谱成像仪Ⅱ、微波成像仪、微波温度计Ⅱ、微波湿度计Ⅱ、红外高光谱大气探测仪、近红外高光谱温室气体监测仪、广角极光成像仪、电离层光度计、空间环境监测器和全球导航卫星掩星探测仪。这10个载荷每天连续对地球探测,并获取数据,卫星将载荷探测数据经过实时空对地广播链路向全球用户广播;同时,通过延时空对地广播链路将全球延时数据对国内的广州、乌鲁木齐、佳木斯、喀什,北极及南极站进行数据下传,这四个国内站及两个极地站收到全球数据后,在45 min内,通过地面商用通信链路将数据传送到数据处理中心,数据处理中心对收到的数据进行汇集、分包、质量判断、预处理、产品生成等处理后,通过专线或互联网将数据发送给用户;同时,各气象、海洋及其他用户还可以通过用户利用站进行数据的接收及应用。
英文摘要:
      FY-3D meteorological satellite have 10 loads: Medium Resolution Spectral Imager Ⅱ, Micro-Wave Radiation Imager, Micro-Wave Temperature Sounder Ⅱ,Micro-Wave Humidity Sounder Ⅱ,High Spectral Infrared Atmospheric Sounder (upgraded from filter type spectrometer IRAS), Greenhouse Gases Absorption Spectrometer, Wide-field Aurora Imager, Ionospheric Photometer, Space Environment Monitor, and GNSS Radio Occultation Sounder. These 10 loads continuously detect the earth and get data every day. The satellite will transmit the data acquired by the payload through real-time space to ground downlink to global users. At the same time, data are transmitted to Guangzhou, Urumqi, Jiamusi, Kashi, the Arctic, and the Antarctic stations through time-lapse DPT downlink. After the six stations receive the data, in 45 minutes, the data are sent to the data processing center through the commercial communication link on the ground. The data processing center collects and subcontracts the received data, judges the quality, preprocesses the data, generates products, and finally sends the data to users through special lines or the Internet. At the same time, the meteorological, oceanic and other users can also receive and apply the data through user's stations.
