Based on the data set of the China"s basic elements of meteorological radiation (V2.0) archived by the National Meteorological Information Centre, a dataset of 1991-2020 China Surface Meteorological Radiation Climate Normals is developed. During the development of the dataset, a systematic quality check and verification revision of the metadata of the ground radiation station observation dataset since 1991 was carried out. Based on the site migration information of the observation station and the radiation observation history documents, the time nodes of manual observation to automatic observation were counted, and the segmentation information needed for climate statistics was established. A set of radiation climate background fields unified as automatic observation methods with better representation was provided. Based on the hourly radiation data of the China"s basic elements of meteorological radiation (V2.0), the hourly annual climate normal of China"s surface meteorological radiation is obtained. Compared with the hourly radiation climate value of China"s surface meteorological radiation from 1981 to 2010, it provides a higher temporal resolution of the radiation climate value statistics, and has a wider application value. 1991-2020 China Meteorological Radiation Climate Normals provides the climatic background information of the hourly (daily, monthly, annually) total radiation, net total radiation, scattered radiation, vertical direct radiation, horizontal direct radiation and reflected radiation of about 103 stations in China (including the mean value, cumulative value, extreme value and occurrence date), providing data support for weather and climate research.
