According to reports, the update time has been shortened from 6 hours to 4 hours, the weather forecast time has been extended by 24 hours, the weather forecast accuracy has been improved by 3%, and the disaster monitoring time has been nearly doubled... This is the latest "performance report" to be submitted by Fengyun-308, which has been "put on duty" in space. At 3:28 on the 27th, China successfully launched the Fengyun-308 satellite into orbit using the Long March 4C carrier rocket from the Jiuquan Satellite Launch Center. The satellite entered its designated orbit and the launch mission was a complete success. The Star Arrows are all developed by the Eighth Academy of China Aerospace Science and Technology Corporation. According to Shao Yikai, the designer of Fengyun-3 08 satellite in the Eighth Academy, Fengyun-3 08 satellite is the 8th satellite in China's second-generation low orbit meteorological satellite series Fengyun-3, and also the 22nd satellite successfully launched by Fengyun-3 meteorological satellites in a row. It has a launch weight of about 2780Kg and operates in a sun synchronous orbit at an altitude of 830km and an inclination angle of 98.7 °. Its main tasks are to achieve weather forecasting, carry out atmospheric chemistry and climate change monitoring. The satellite is equipped with 9 remote sensing instruments, including a medium resolution spectral imager, an infrared hyperspectral atmospheric detector, a microwave thermometer, a microwave hygrometer, a microwave imager, a global navigation satellite occultation detector, a hyperspectral greenhouse gas monitor, an ionospheric photometer, and a wide-angle aurora imager. It will achieve high-precision global greenhouse gas fine detection with a width of 100 kilometers for the first time internationally. With the support of numerous advanced equipment, Fengyun-3 08 satellite has high quantitative accuracy and spectral calibration accuracy reaching the picometer level. Strong comprehensive ability, able to achieve full spectrum and quantitative observation on the same platform. On the basis of achieving comprehensive atmospheric remote sensing detection of temperature, humidity, wind, rain, clouds, and other elements, it is possible to simultaneously obtain remote sensing information on global greenhouse gases, auroras, ionosphere, and other factors. ”Shao Yikai said. In addition, Fengyun-308 satellite also has the capability to monitor ice and snow cover and sea surface temperature in orbit, providing remote sensing information needed for short-term climate prediction and climate change estimation; Obtain global atmospheric chemical distribution; In orbit monitoring of natural disasters, ecology, and environment; Capable of conducting auroral and ionospheric data monitoring in orbit. After the Fengyun-3 08 satellite takes up its post in space, it will network with the 05, 06, and 07 satellites to achieve 100% coverage of global observation data and ensure core meteorological services. ”Shao Yikai said, "Satellites in orbit will obtain meteorological parameters required for numerical forecast assimilation applications. The data update time will be shortened from 6 hours to 4 hours, the meteorological forecast time will be extended by about 24 hours, the meteorological forecast accuracy will be improved by about 3%, and the disaster monitoring time will be nearly doubled, which will effectively enhance the weather prediction and forecasting capabilities
