Shulou(Shulou.com)11/24 Report--

CTOnews.com November 13 news, according to the National Weather Administration, November 13, Fengyun 3F Star (hereinafter referred to as "F Star") the first set of maps officially released to the public. At present, all remote sensing instruments have been turned on, which indicates that the satellite platform and remote sensing instruments have entered the steady-state work and will step into the stage of in-orbit testing.

As previously reported by CTOnews.com, F was successfully launched on August 3 this year. As the "successor" of Fengyun 3C, it is also a solar synchronous morning orbit satellite, and will continue to carry out global earth-atmosphere system integrated exploration business. Compared with C star, the spectral channel of F star increases nearly 50 times, and the measurement accuracy and stability are steadily improved.

The first global image of ▲ Fengyun 3F moderate Resolution Spectral Imager, Source National Satellite Meteorological Center

The first picture of ▲ Fengyun 3 F satellite microwave imager, the first set of F satellite images of the National Satellite Meteorological Center relies on its ten remote sensing instruments, that is, 2 newly developed ultraviolet hyperspectral instruments, 3 improved instruments and 5 inherited instruments, a total of four types of observation data are released, including atmospheric composition observation data, imaging observation data, detection data and earth-atmosphere system radiation budget observation data.

The first picture of the newly developed ultraviolet hyperspectral ozone edge detector clearly shows its ability to detect stratospheric atmospheric composition information above the ground. Through cooperative observation with the ultraviolet hyperspectral ozone detector, the monitoring of the total and vertical distribution of trace gases such as ozone, nitrogen dioxide and sulfur dioxide can be enhanced.

The ultraviolet hyperspectral atmospheric composition detection of ▲ Fengyun 3F satellite shows that F satellite has the optical imaging ability of 100 meters, and the medium resolution spectral imager can realize daily global seamless observation, and its rich channel information can be used to obtain the main core climate variables of the earth-atmosphere system. Global clear sky images can be generated by multi-day data synthesis technology. At the same time, the microwave imager can obtain kilometer microwave imaging data, and its all-weather and all-weather observation capability will provide important support for global environmental monitoring and disaster prevention and mitigation.

In terms of detection data, F satellite uses three advanced atmospheric vertical sounding instruments, such as microwave thermometer, microwave hygrometer and infrared hyperspectral atmospheric sounder, to scan the earth-atmosphere system by CT, carry out cooperative observation of microwave and infrared spectrum, and obtain vertical information of atmospheric temperature and humidity, which provides data support for global numerical weather forecast.

Fengyun 3 D, E, F and G satellites have formed a network, which will further give full play to the overall advantages of the complete observation network of Fengyun Leo meteorological satellites.

Hu Xiuqing, chief engineer of the ground system of Fengyun-3 meteorological satellite, said that the next step will be to vigorously promote the opening and sharing of information and achievements. It is expected that F Star will put into trial operation in March next year and provide global data services to actively perform its duties in the "Morning Star" position.

In addition, the development of China's Fengyun No. 3 04 satellite project has been launched, which is the end of the second generation of Leo meteorological satellites in China, including a tilt orbit precipitation measurement satellite and a sun synchronous dawn orbit satellite. It will further improve the load detection capability and platform service support capability, and will cooperate with high-orbit meteorological satellites to realize on-orbit verification of high-and low-orbit cooperative observation in China for the first time. Support the intelligent observation and system development of the third generation meteorological satellites.
