The China Meteorological Administration (CMA) on Wednesday unveiled the CMA Global Climate Dataset at the 4th China-ASEAN Meteorological Cooperation Forum in Nanning, south China's Guangxi Zhuang Autonomous Region. It marks China's first international sharing of high-value climate data products, according to the CMA.

The dataset has six categories: global surface and upper-air datasets, grid-based reconstructions, CMA's global atmospheric reanalysis, Fengyun satellite land-surface and radiation datasets, and ocean datasets. The CMA said the data match international standards and supports applications such as early warning systems, disaster mitigation, AI development and climate research.

The CMA Global Climate Dataset is now accessible through international channels, including the English versions of the China Meteorological Data Network and the World Meteorological Centre (Beijing) website.

The forum also launched the China-ASEAN Joint Innovation Action for AI Meteorological Model Application, an initiative to co-develop advanced AI weather prediction models aimed at improving forecasts for severe events such as typhoons. The action plan focuses on four key areas: joint innovation, data integration, talent cultivation and building a shared collaborative platform known as the "China-ASEAN Meteorological Home."

Held under the theme "Digital Intelligence Empowers Meteorological Cooperation," the forum brought together officials from China, ASEAN member states, and the World Meteorological Organization. Speakers highlighted the transformative potential of AI in meteorology and reiterated their support for advancing the UN's "Early Warnings for All" initiative.
