The Fengyun-3G satellite, designed to measure Earth’s precipitation, commenced its operational services on Wednesday, following its launch in April, as announced by the China Meteorological Administration.
China’s FY-3G, the inaugural low-orbit satellite dedicated to precipitation measurement, is capable of monitoring severe weather conditions and delivering three-dimensional precipitation data.
Chen Lin, the deputy chief designer of the FY-3G ground system, mentioned that the global observation of precipitation, especially the three-dimensional structures, presents a challenge in meteorological detection.
The deployment of the FY-3G satellite marks an advancement in the nation’s capabilities for observing global precipitation and detecting three-dimensional structures, he stated.
Since October, the satellite has successfully undergone more than six months of operational trials, maintaining stable performance of the satellite-ground system. The capabilities for receiving, processing, and archiving data have all achieved the required standards.
The satellite has significantly bolstered meteorological services for major events, including last year’s Asian Games in Hangzhou. Additionally, it has supplied data for flood monitoring in Pakistan and the recent intense rainfall in Yemen, according to Chen.
Since 1988, China has successfully launched 21 independently developed Fengyun meteorological satellites, of which nine are currently in operation.
The FY-3G, as the 20th satellite in the Fengyun series, is the first in the world to utilize a combination of active precipitation measurement radar, passive microwave, and optical remote sensing. This innovation signifies a shift from passive observation to active probing in satellite technology.
The integration has improved China’s extensive meteorological observation capabilities, as stated by the administration.
The FY-3G satellite is capable of capturing critical data, including the internal temperature and humidity of typhoons, as well as the intensity and affected areas. This information is crucial for predicting the development of typhoons and accurately monitoring associated rainfall events.
The China Meteorological Administration, in collaboration with the Ministry of Emergency Management and other agencies, has indicated that there may be an uptick in heavy rainfall across China in May, especially in the southern and northwestern regions, which could heighten the risk of geological disasters.
