Temperature, precipitation and sunshine across China, 1912-51: A new daily instrumental dataset

This project compiled 463,530 instrumental observations of daily temperature, precipitation, and sunshine at up to 319 stations in China between 1912-51. The principal sources are monthly reports of the Institute of Meteorology, Nanjing, observatories in Japanese-occupied Manchuria, and the Japanese Army in North China. Gross errors, rounding errors, and inhomogeneities are identified. The new dataset is temporally and spatially consistent with existing datasets of monthly temperature, but reports higher precipitation and sunshine.
