中国气象数据服务惠及全球153个国家和地区

Core Viewpoint - China's meteorological data services have reached 153 countries and regions, significantly contributing to climate change research, agricultural adaptation, disaster warning systems, AI meteorological model training, and energy forecasting since the release of the "International Sharing Directory of China's Climate Data Products" in September last year [1]. Group 1: Data Sharing and Usage - Since the release of the climate data products directory, there have been nearly 4.16 million visits from foreign users, indicating a strong international interest in China's meteorological data [1]. - By 2025, China is expected to share approximately 23.5TB of data annually through GTS/WIS, and around 320TB through WIS2.0, enhancing global data accessibility [2]. - The CMACast system will provide 136.6TB of data annually to users in 17 countries, including Mongolia and the Maldives, showcasing China's commitment to international data sharing [2]. Group 2: Infrastructure and Support - China has established a robust infrastructure for data sharing, including GTS, WIS2.0, CMACast, and overseas cloud nodes, facilitating efficient cross-border transmission of meteorological data [2]. - The overseas cloud nodes in Singapore and Cairo are part of a warning network covering climate-vulnerable areas along the Belt and Road Initiative, enhancing regional disaster preparedness [2]. Group 3: International Collaboration - The Chinese Meteorological Administration (CMA) has been actively involved in international meteorological governance and cooperation, fostering partnerships with major global meteorological organizations [3]. - The collaboration with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) has been ongoing for over 20 years, exemplifying mutual benefits in satellite observation, data exchange, and service applications [3]. - The European Centre for Medium-Range Weather Forecasts (ECMWF) has recognized the partnership with CMA as beneficial for improving best practices and enhancing professional capabilities [3]. Group 4: Future Directions - The CMA plans to continue systematic and large-scale data sharing, transforming China's observational and forecasting data into reliable international public goods to support global climate change responses and sustainable development [4].
