China has taken a significant step in advancing global weather monitoring with the official operation of its first precipitation measurement satellite, the Fengyun-3G (FY-3G). Launched on April 16, 2023, FY-3G operates in a low-inclination orbit, providing critical data for precipitation climatology research and systematic monitoring of disastrous weather events.
The FY-3G satellite offers three-dimensional structure information of precipitation in middle and low latitude regions, a capability that has long been a challenge in meteorological detection. Chen Lin, deputy chief designer of the FY-3G ground system, highlighted in an interview with China Media Group (CMG) that the satellite addresses a persistent difficulty in global precipitation observation.
Since its launch, FY-3G has completed over six months of trial operation, during which the satellite-ground system has maintained stable performance. All four assessment indicators—data reception, data processing, product distribution, and data archiving—have met the required standards.
Chen Lin emphasized the satellite's vital role in supporting major events and disaster monitoring. \"Throughout the year, the FY-3G has not only provided strong and powerful support for weather service guarantees for China's Universiade, Asian Games and other events, but also provided support for monitoring global disasters such as floods in Pakistan, heavy rainfall in Brazil and the recent heavy rainfall in Yemen,\" he stated.
The successful launch of FY-3G makes China the only country to operate four civilian meteorological satellites in near-Earth orbit simultaneously, covering morning, noon, afternoon, and inclined orbital paths. This comprehensive coverage enhances China's ability to monitor weather patterns and respond to natural disasters effectively.
The Fengyun meteorological satellite system, developed independently by China, has been a cornerstone of the country's meteorological capabilities since the launch of its first satellite in 1988. To date, 21 Fengyun meteorological satellites spanning two generations and four types have been successfully deployed, with nine still in orbit. Over the years, Fengyun satellites have achieved international advancements, with some of their technologies leading the global market.
