Southeast Asia Information Port (www.dnyxxg.com) – According to the National Meteorological Information Center, since the release of the "International Sharing Catalog of China's Climate Data Products" last September, this batch of datasets has attracted nearly 4.16 million visits from international users and has been widely used in several key areas, including climate change research, agricultural climate adaptation, disaster early warning system development, artificial intelligence meteorological model training, and energy forecasting.
In recent years, the China Meteorological Administration has continuously strengthened data sharing, providing support to multiple key sectors globally. Through diverse channels such as the Global System for Telecommunications (GTS), the World Meteorological Organization's Information System (WIS) 2.0, the China Meteorological Administration's Satellite Data Broadcasting System (CMACast), Fengyun satellite data direct receiving stations, and overseas cloud nodes, China provides high-quality meteorological data services to 153 countries and regions worldwide, providing strong support for international scientific research and disaster prevention practices.
By 2025, in accordance with the World Meteorological Organization (WMO) global exchange agreement, China will distribute and share ground and upper-air observation data, Fengyun satellite monitoring data, numerical weather prediction and warning products, as well as multi-source data from commercial aircraft and ships, in real time globally through GTS/WIS, with an annual shared data volume of approximately 23.5TB; through WIS2.0, it will share approximately 320TB of data in real time with relevant governments and institutions worldwide; through CMACast, it will broadcast ground observation data, Fengyun satellite data, and global numerical weather prediction products to users in 17 countries, including Mongolia and the Maldives, with an annual service data volume of 136.6TB per user; and through Fengyun satellite data direct receiving stations, it will broadcast Fengyun satellite data products in real time to countries such as Mozambique, Namibia, Mongolia, and Kyrgyzstan.
Simultaneously, relying on overseas cloud nodes deployed in Singapore and Cairo, North Africa, China will build an early warning network covering climate-vulnerable areas along the Belt and Road Initiative with Beijing, achieving efficient cross-border transmission of meteorological data. In 2025, the global data service received 5.17 million visits and downloaded 38.9TB of data. Its service coverage expanded to South Asia, Southeast Asia, the South Pacific, and Africa, effectively supporting meteorological operations in more than 10 countries, including Ethiopia and the Maldives, and promoting the international adoption and application of China's nationwide early warning system, "MAZU."
As an important window for global data services, the English versions of the China Meteorological Data Network and the Fengyun Satellite Remote Sensing Data Service Network have consistently provided convenient data sharing services to international users since their inception. Their stability and user-friendliness have been widely praised by international users. The English version of the China Meteorological Data Network continuously provides services such as data discovery, multi-dimensional navigation, flexible retrieval, and visualization for global climate data products developed by the China Meteorological Administration (CMA). It provides crucial data support for early warning of meteorological disasters and global disaster prevention and mitigation, and assists in the research and application of artificial intelligence technologies and cutting-edge research in the field of climate change. The English version of the Fengyun Satellite Remote Sensing Data Service Network provides online retrieval, subscription, and download functions primarily based on Fengyun satellite data, and offers online application platforms such as Fengyun Earth, providing international users with customized and visualized data functions such as online real-time cloud image browsing, disaster monitoring, and model verification.
The CMA has long been actively involved in international meteorological governance and cooperation, continuously deepening its partnerships with major global meteorological agencies and promoting the two-way exchange of data, technology, and experience. Its cooperation with the European Organization for the Development of Meteorological Satellites (EUMETSAT) has spanned over two decades, becoming a model of mutual benefit and win-win cooperation in the international meteorological field. Both sides have made significant progress in satellite observation, data exchange, and application services. Experts from the European Centre for Medium-Range Weather Forecasts (ECMWF) commented that the cooperation with the China Meteorological Administration (CMA) is not only mutually beneficial in terms of data sharing, but also helps both sides continuously benefit in improving best practices and jointly enhancing professional capabilities.
Going forward, the CMA will continue to systematically and on a large scale share data, transforming China's observational, forecasting, and meteorological satellite data into reliable international public goods, contributing Chinese strength to global efforts to address climate change, enhance disaster prevention and mitigation capabilities, and achieve sustainable development.
