Short summary
(1) The SPEI has been widely used to monitor and assess drought characteristics. (2) A multi-scale daily SPEI dataset was developed across mainland China from 1961 to 2018. (3) The daily SPEI dataset can identify the start and end days of a drought event. (4) The daily SPEI dataset developed is free, open, and publicly available from this study.
