In the sequence of China's Fengyun meteorological satellite, this star is the fourth satellite of the second generation polar-orbiting meteorological satellite Fengyun No.3, and the 16th Fengyun satellite. The launch was carried out by the Long March 4C carrier rocket, and it was also equipped with a launch of the "Heide 1" test satellite. It can improve the mid- and long-term weather forecasting ability to locate the auroral boundary.
The reporter learned from the China Meteorological Administration that at 2:35 on November 15, 2017, China used the Long March 4 C carrier rocket at the Taiyuan Satellite Launch Center to successfully launch the "Fengyun No. 3" meteorological satellite, and the satellite successfully entered the reservation. track.
Fengyun No.3 D is equipped with an infrared hyperspectral atmospheric vertical detector. This instrument adopts the most advanced Fourier interference detection technology in the world, which can improve the atmospheric temperature and atmospheric humidity profile inversion accuracy by more than one time. Improve the support for China's medium and long-term numerical weather prediction, and extend the effective time limit of weather forecast for 2-3 days.
The "Fengyun No.3" meteorological satellite is China's second generation of polar orbiting meteorological satellite, which can realize global, all-weather, multi-spectral, three-dimensional, quantitative remote sensing. After the launch of Fengyun No.3D, it will be put into operation after the on-orbit test, and become the main operational satellite of low-orbit observation in China. It will be jointly set up with Fengyun No.3 C launched in September 2013 to further improve the accuracy of atmospheric detection and enhance the greenhouse. Gas monitoring, comprehensive detection of space environment and meteorological remote sensing capability will promote the comprehensive application of meteorological satellites and provide important support for promoting ecological civilization construction, national comprehensive disaster prevention and mitigation, and “Belt and Road†construction.
By then, China will become the country with the largest number and variety of on-orbit meteorological satellites in the world.
Currently the largest satellite in ChinaThe "Fengyun No.3" satellite and the Long March 4C carrier rocket carrying out the launch mission were developed by the Shanghai Aerospace Technology Research Institute of China Aerospace Science and Technology Corporation. The measurement and control tasks were jointly completed by Xi'an Satellite Measurement and Control Center and China Satellite Maritime Monitoring and Control Department. The China Meteorological Administration is responsible for the construction and operation of the satellite application system. This is the 254th flight of the Long March series of launch vehicles.
“Fengyun No.3D is currently the largest satellite measuring channel in China, with nearly 7,000 measuring channels,†said Zhang Peng, deputy director of the National Satellite Meteorological Center, and the chief commander of the Fengyun No. 3 polar orbiting meteorological satellite engineering ground application system. Greatly improve the detection of low-level atmospheric dynamic parameters, thermal parameters, greenhouse gases and high-level atmospheric electric, magnetic, and high-energy particles, and improve China's global numerical weather prediction, global climate change response, ecological environment monitoring, and space weather forecasting. Ability and level.
In an interview with reporters, Zhang Peng said that Fengyun No. 3 is the fourth satellite of China's second-generation polar-orbiting meteorological satellite, which will replace the Fengyun No. 3 B satellite launched in 2010 and carry out comprehensive global observation of the ground in the afternoon.
"In terms of overall positioning, it is a guarantee for China's global low-orbit satellite observation capability, and it is the inheritance of Fengyun No. 3 B business observation capability, and also the improvement and improvement of Fengyun No. 3 B observation capability." Zhang Peng said. Fengyun No.3 D Star will support China's numerical weather forecasting service in the future and will also play an important role in global meteorological disaster prevention and mitigation.
Serving 77 countries and regionsChina has successfully launched 15 meteorological satellites, currently 8 in orbit, of which 7 operations, providing a large number of global and regional Earth observation information for meteorological, marine, forestry, agricultural, civil aviation and military applications.
Fengyun Meteorological Satellite has become a terrestrial observation satellite representing China's strength and with a wide international reputation. It has been included in the global Earth observation service satellite sequence by the United Nations World Meteorological Organization, and has improved the forecast of the most advanced medium- and long-term numerical weather prediction models in China and internationally. Timeliness and precision.
Fengyun Meteorological Satellite also undertakes the Chinese duty satellite mission of the International Disaster Reduction Charter Mechanism and plays an increasingly important role in the international meteorological disaster prevention and reduction work.
According to the incomplete statistics of the China Meteorological Administration, there are 77 countries and regions that receive and apply the Fengyun series of meteorological satellite data, covering 37 countries and regions around the Belt and Road.
The development of Fengyun meteorological satellites has improved the global observation capability of China's meteorological satellites and made positive contributions to global economic and social development. On the other hand, it has significantly enhanced China's ability to participate in global competition and enhanced China's disaster prevention and mitigation. The right to speak in international activities such as global climate change response, ecological environment monitoring and conservation.
