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.
