From: The first global multi-timescale daily SPEI dataset from 1982 to 2021
Statistically significant (p < 0.05) correlation between SPEI-GD, SPEIbase and soil moisture at the timescales of 180 days and 6 months during 1982–2020 in different climate regions. (a) Spatial pattern of global climate regions classified based on AI. (b) Correlation between SPEI-GD and SSM. (c) Correlation between SPEIbase and SSM. (d) Correlation between SPEI-GD and RSM. (e) Correlation between SPEIbase and RSM.
