On 21:07 p.m. BJT, June 5, the Fengyun-2H meteorological satellite, carried by a Long March-3A rocket, was launched from the Xichang Satellite Launch Center in southwest China's Sichuan Province. As the westernmost on-duty satellite in geostationary meteorological satellites layout of China, FY-2H can provide custom-made services for countries along “Belt and Road” territories, and data support for weather prediction and disaster prevention and mitigation.

Countries along “Belt and Road” territories are deficient in meteorological data and subject to grave natural disasters. In response to a request from the World Meteorological Organization (WMO) and the Asia-Pacific Space Cooperation Organization (APSCO), the setpoint position of the newly launched Fengyun-2H will be placed westward. State Administration of Science, Technology, and Industry for National Defence, China Meteorological Administration (CMA) and APSCO signed an intent of cooperation to finalize that FY-2H be moved westward by 7.5°, to 79°East.

FY-2H is positioned over Indian Ocean and has realized the sustained observation of one third of the Earth’s territories from Oceania to Central Africa and can provide favorable observation perspectives and custom-made high frequency sub-regional observation for countries and regions like West Asia, Central Asia, Africa, and Europe. FY-2H, equipped with a scanning radiometer and space environment monitor, can supply dozens of remote sensing products like cloud images, clear sky atmospheric radiation, sand and dust, and Cloud Motion Wind (CMW) for weather prediction, disaster early warning, and environmental monitoring, and enrich data sources of global NWP models.

Mr. Lu Feng, deputy chief designer of FY-2 ground application system remarked that if a large-scale cargo vessel departed from Shanghai port in China and reached the Red Sea via South China Sea, Strait of Malacca, Indian Ocean, and Gulf of Aden, it could enjoy 24-hour uninterrupted meteorological satellite observation services.

According to Mr. Sun Jun, chief forecaster of National Meteorological Center (NMC), FY-2H with a distinctive position will be instrumental in unraveling the “atmospheric code” of upper reaches weather system in China and assisting forecasters in timely grasping weather system evolution by observing weather systems like cold wave, and precipitation and cloud belts in Central Asia and areas over Indian Ocean.

With the Emergency Support Mechanism for International Users of FengYun Meteorological Satellites in Disaster Prevention and Mitigation, if countries along the Belt and Road or APSCO member states are gripped by disasters like typhoons, rainstorms, sandstorms and forest or prairie fires, they can apply to activate dedicated observation by Fengyun satellites. At that time, FY-2H, equipped with high frequency sub cloud images at 6-minute intervals, and related quantitative product service abilities, can offer timely decision-making support for disaster prevention and mitigation.

Fengyun-2H is the last in the FY-2 series. After the launch, FY-2H will conduct a four-month in-orbit testing. By that time, China will distribute gratuitous satellite data and products to international users. (Jun. 6)
