Beijing, 24 Mar (Xinhua) -- On March 23, a Fengyun-3 satellite, as usual, was running smoothly in a given orbit, flying to the Vietnamese North Pole, circling the azure earth twice, and transmitting a large amount of data to the Fengyun Meteorological Satellite Data Service Network.
At fixed times a day, the polar-orbiting satellite also flies twice over The United States of Vietnam and Chile and provides data services to one of its users, the Chilean Meteorological Agency.
In the eyes of Cristóbal Torres, a meteorologist at the National Analysis Center of the Chilean Meteorological Bureau, China's Fengyun meteorological satellites are "professional, advanced and easy to use", and he has also been committed to studying how to promote and use this technology in China.

In 2018, the Fengyun-4 satellite product application international training course was held in Beijing, and Torres became one of the 22 participants in the training. Although he has been back to China for more than three years, he still clearly remembers many details of the trip to China.
"It was a wonderful experience. At the China Meteorological Administration, we saw first-class equipment, advanced management, and a modern information release channel. Torres said.
The 2018 training focused on the application of the Fengyun-4 satellite. Although the satellite does not cover Chile, Torres believes that such learning opportunities are precious and "the more the merrier".
Torres said that in Chile, meteorological satellite data applications are still a new field, they need more information and data to help improve the level of forecasting, and hope to have the opportunity to learn more about relevant experience and knowledge, and share the observation data of Fengyun satellites.

Torres is currently responsible for analyzing short- and medium-term weather forecast data at the Chilean Meteorological Agency and disseminating weather information to the public and related agencies.
Chile has a long and narrow terrain with a Mediterranean climate in the middle, with high temperatures and little rain in the summer and cold and humid winters; in the south, it is affected by westerly winds from the Pacific Ocean, and there is more rainfall throughout the year. Faced with such a complex and changeable weather in Chile, Torres and his colleagues have to deal with a large amount of satellite data every day, much of which comes from the "Fengyun Meteorological Satellite Family".
As early as 2018, during the training, Torres learned about the advantages of the Fengyun Meteorological Satellite. He said that the data website of Fengyun Meteorological Satellite is very user-friendly, and the polar-orbiting satellites are "very helpful" to them, which greatly improves their forecasting capabilities.
Torres also stressed the importance of real-time satellite data for disaster prevention and relief. He explained that Chile has a large area of forest, and real-time satellite data can be very useful for knowing when fires occur and taking corresponding fire fighting actions. In 2018, Fengyun Satellite provided data services for Chile's response to forest fires.
"China has reached world-class levels in meteorological satellite observation technology. The data obtained by these satellites is very useful for the countries they cover, especially for developing countries. Torres praised. He hoped that in the future, Chile and China can further deepen cooperation in technical analysis, product research and development, and climate change research.

Fengyun Meteorological Satellite is independently developed by China, and Xian Di, deputy director of the International User Service Center of the National Satellite Meteorological Center of China, introduced that after more than 50 years of development, China has successfully launched 19 Fengyun meteorological satellites, including polar orbit and geostationary meteorological satellites. At present, 8 satellites are operating stably in orbit. Many satellites of the "Fengyun family" have become the duty satellites of the International Charter Mechanism for Space and Major Disasters.
According to the China Meteorological Administration, as of February 2022, Fengyun Satellite has provided data services to 121 countries and regions around the world, including about 90 countries and regions along the "Belt and Road".
"Science and technology is a bridge for exchanges and cooperation among countries. Fengyun Meteorological Satellite serves 121 countries and regions around the world, which is a vivid embodiment of the landing of scientific and technological innovation and the global application of technology application services. Fengyun satellite now carries out global services every day, especially the Fengyun-2 H star has a nickname, called the 'Belt and Road' star, I think it is precisely because it undertakes the mission of serving the 'Belt and Road' countries. Xiandi said. (Reporters: Chen Yao, Yin Nan, Huang Shunda; Editors: Huang Shunda; Editors: Wang Zhao, Zhang Zhongxia, Peng Qian, Wang Shen, Lu Yu)
