On the morning of June 10, Chinese President Xi Jinping delivered a commitment during the Shanghai Cooperation Organization (SCO) Summit held in Qingdao that China was willing to provide meteorological services for all members of SCO by harnessing FY-2 meteorological satellites.

On June 5, prior to the Summit, China successful lifted off FY-2H satellite, further optimizing the orbital layout of FY meteorological satellites. At present, FY series meteorological satellites compose of FY-2E, FY-2F, FY-2G and FY-2H will effectively cover regions including member and observer states of SCO like India, Kazakhstan, Kyrghyzstan, Pakistan, Russia, Tajikistan and Uzbekistan, contributing to disaster prevention and mitigation.

SCO member states are predominantly located in territories along the “Belt and Road”. In these regions, meteorological data are scarce and natural disasters abound. Relevant disaster hazards are twice of the global average value, and characterized by meteorological disasters. Before the launch of FY-2H satellite, European geostationary meteorological satellite covering Indian Ocean is near its final stage, which will incur a blank space in geostationary satellite monitoring in the future. In response to a proposal from the World Meteorological Organization (WMO) and the Asia-Pacific Space Cooperation Organization (APSCO), the setpoint position of the newly launched FY-2H is placed westward by 7.5°, to 79°East.

This symbolizes that FY-2H can not only reinforce monitoring of China’s weathering systems, but also form effective coverage of regions where SCO member and observer states reside, thus powerfully supporting disaster prevention and mitigation.

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. It 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.

Currently, the Emergency Support Mechanism for International Users of FengYun Meteorological Satellites in Disaster Prevention and Mitigation established by China Meteorological Administration (CMA) is also applicable to SCO member states. If countries covered by FY geostationary satellites are gripped by disasters like typhoons, rainstorms, sandstorms and forest or prairie fires, they can apply to activate dedicated observation by FY 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.

So far, China has successfully launched 17 FY meteorological satellites, which have been incorporated in the sequence of WMO global operational meteorological satellites as important components of the Global Earth Observation System and also as on-duty satellites of the International Charter on Space and Major Disasters, providing data for more than 80 countries and territories around the world.
