The China Meteorological Administration (CMA) has released its Global Climate Datasets at the 4th China-ASEAN Meteorological Cooperation Forum, marking the first time the country’s climate data products have been made available for international sharing.
The dataset encompasses six categories of data: Global Surface Dataset, Global Radiosonde Dataset, Global Merged Surface Temperature, CMA ReAnalysis V1.5, Fengyun (FY) Satellites Land & Radiation Dataset and FY Satellites Ocean Dataset.
They will support international exchange, provide application services such as meteorological early warning disaster prevention and mitigation, and facilitate global research and development in artificial intelligence (AI) technologies and climate change studies.
The Global Climate Datasets use independently developed products with sophisticated technology and reliable quality from 106 high-value meteorological data products of the CMA.
Among them, daily and monthly values of the Global Surface Dataset and Global Radiosonde Dataset can be traced back as early as 1850, with the longest sequence spanning 176 years.
Based on the compiled data from a global multi-source observational station network, Global Merged Surface Temperature has undergone spatiotemporal reconstruction processing to generate monthly global surface temperature gridded products since 1850, with a spatial resolution of 2°×2°, equivalent to approximately 200km.
The FY Satellites Land & Radiation Dataset and FY Satellites Ocean Dataset have undergone recalibration and consistency correction of historical FY satellite data, forming products such as 5km land surface temperature, radiation, sea surface temperature and sea ice.
The target users of the datasets are those in meteorological forecasting, early warning and in-depth applications of AI. They can be accessed through channels such as the English version of the China Meteorological Data Network, the website of the World Meteorological Center Beijing and the English version of the Fengyun Satellite Data Service.
The CMA says it will continuously evaluate the application effectiveness and smoothness of download channels for internationally shared data products, ensuring sustained high-quality data products and smooth sharing channels.
