Homogenized daily sunshine duration over China from 1961 to 2022 [PDF]

open access: yesEarth System Science Data
Inhomogeneities in the sunshine duration (SSD) observational series, caused by non-climatic factors like China's widespread transition from manual to automatic SSD recorders in 2019 or station relocations, have hindered the accurate estimation of near ...
