At 9:36 a.m. on April 16, a Long March-4B rocket blasted off from the Jiuquan Satellite Launch Center in northwest China and soon sent the FENGYUN-3G meteorological satellite(FY-3G) into its preset orbit. It is the third precipitation measurement satellite in the world which can realize proactive measurement. Since then, China has become the only country in the world which operates meteorological satellites in four near-earth orbits.


FY-3G is equipped with 4 operational payloads, namely, Ku/Ka-band dual-frequency precipitation measurement radar, microwave imager, as well as optical imager and near-infrared multi-angle polarization imager. Its main payload, precipitation measurement radar, is first of its kind which is independently developed in the country. Its ground system can provide data and IT resources supporting platform for its operational application, and realize the quality surveillance of operational data throughout the whole procedure.

Dr. CHEN Zhenlin, Administrator of China Meteorological Administration (CMA) congratulated the successful launch of FY-3G, and paid high tribute the distinguished contribution made by meteorological and aerospace science and technology practitioners to the development of FY meteorological satellite cause. He pointed out that FY-3G was 20th FY meteorological satellite among the FY meteorological family. Its successful launch has further completed the low-orbit meteorological satellite constellation networking layout, was instrumental in giving full play to the advantage of low-orbit meteorological satellite observing network of China, and would markedly improve the capability of early warnings of global disasters like rainstorm.

Prof. Petteri Taalas, Secretary-General of WMO congratulated on the launch of FY-3G. For several decades, he has been following the development of FY meteorological satellite program. He remarked that FY satellites are of state-of-the-art level in the world, and their data were useful for many sectors in many countries, in particular, less developed countries. He thanked the open data policy in China’s meteorological satellite field for playing a role in global meteorological capacity development.

Dr. ZHANG Wenjian, Assistant Secretary-General of WMO expected that FY-3G would contribute to global precipitation monitoring and freshwater resource survey, make remarkable contributions to disaster prevention and reduction, realizing the vision of Early Warnings for All Initiative, and the assessment of the impact of global climate change on global precipitation distribution. The successful launch of FY-3G was China's vital contribution to the world.

Dr. ZHANG Zuqiang, Deputy Administrator of CMA, commented that FY-3G will be a major initiative to protect the safety and wellbeing of the people, and it will carry out in-orbit testing. Meteorological practitioners should conscientiously make every endeavor to make sure the data of FY-3G will be soon applied in the work during this year's flood season.

Dr. CAO Xiaozhong, commander-in-chief of FY meteorological satellite program, and Deputy Administrator of CMA, expressed that FY-3G was the first satellite in China to proactively measure the precipitation, will be applied in severe weather monitoring and forecasting, and will play a role in fields like ecological environment, energy, agriculture, and health.

Mr. Phil Evans, Director-General of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), stated that FY-3G would help negate the sometimes destructive impact of severe weather occurrences on economies and societies and he was very proud of the excellent bilateral cooperation. Through bilateral operational data exchange agreement, EUMETSAT ensures that CMA data, which will shortly include those of FY-3G, reaches the operational user community in Europe. He also anticipated a further bilateral collaboration.

Mr. CHEN Tao, chief forecaster from National Meteorological Centre (NMC) expressed that FY-3G would further deepen the insight into the three-dimensional structure of precipitation and cloud, and micro-physical feature of cloud, and anticipated its operational application in weather forecasting.

In the next 6 months, FY-3G will carry out in-orbit testing, in a bid to verify its indicators in terms of satellite platform, payloads and others, and tackle meteorological disasters like rainstorm and typhoon during the main flood season.

China will launch another FY-3 meteorological satellite in August. So far, China has 8 FY meteorological satellites in orbit, providing data products and services for 126 countries and regions in the world.
