Many meteorological satellite tv for pc networks are continuously scanning Earth, offering important analysis information and real-time life-saving climate data. Since China started its preliminary improvement in 1970, the Fengyun (FY) sequence of meteorological satellites have superior significantly all through greater than 50 years. While FY satellites primarily give attention to the ambiance, they’re able to observing advanced variables throughout the Earth-atmosphere system. Since the preliminary FY dispatch, China has efficiently launched 17 FY satellites, seven of that are presently working in orbit.

The Fengyun Meteorological Satellite Ground Application System generates greater than 90 Earth remark merchandise each day, producing greater than 10TB of day by day information quantity. The FY Satellite Data Center has repeatedly saved Earth remark information, starting when FY-1A efficiently launched in 1988, to at the moment. More than 12PB of archived satellite tv for pc information exists within the database by greater than 30 years.

“Several approaches for FY satellite data access have been developed for real-time users, scientific researchers, and public users.” mentioned Dr. Peng Zhang, the deputy director of National Satellite Meteorological Center of China Meteorological Administration. “All FY satellite data products are open to the world users and free to download.”

Dr. Zhang can also be the corresponding creator of a knowledge description article lately printed in Advances in Atmospheric Sciences. The article showcases FY information merchandise used to look at wildfires, lightning, vegetation indices, aerosol merchandise, soil moisture, and precipitation estimation. All of those metrics have been validated with in-situ observations and have been cross referenced with different well-known satellite tv for pc merchandise.

The European Centre for Medium-Range Weather Forecasts (ECMWF) and climate forecasting companies in China have assimilated the big selection of FY information into many numerical climate prediction (NWP) fashions. Since the 1990s, coupled meteorological satellites and numerical fashions have modified the best way scientists perceive the Earth. As numerical climate prediction and Earth system fashions proceed to evolve, meteorological satellites will play a extra vital function in the way forward for Earth sciences.

“FY is included in the World Meteorological Organization’s global operational meteorological satellite sequence. It provides data and products to more than 110 countries and regions as well as 2,700 broadcasting users.” Dr. Zhang added. “We have been working with scientists from ECMWF, UK MetOffice, and other countries to improve data verification and application. We welcome scientists and forecasters all over the world to use FY data.”
