From: The first global multi-timescale daily SPEI dataset from 1982 to 2021
Statistically significant (p < 0.05) correlation between daily SPEI-GD, SPEIbase and soil moisture at the timescales of 180 days and 6 months during 1982–2020. (a,b) Surface soil moisture (SSM). (c,d) Root zone soil moisture (RSM). (e) The time series of global mean SSM, RSM and SPEI-GD, where R indicates the correlation coefficient.
