Data sets
Global soil moisture simulated by SoilClim and mHM models at 0.5° resolution for the 1980–2022 period Jan Řehoř et al. https://doi.org/10.5281/zenodo.11395946
Short summary
We present a robust method for identification and classification of global land drought events (GLDEs) based on soil moisture. Two models were used to calculate soil moisture and delimit soil drought over global land from 1980–2022, with clusters of 775 and 630 GLDEs. Using four spatiotemporal and three motion-related characteristics, we categorized GLDEs into seven severity and seven dynamic categories. The frequency of GLDEs has generally increased in recent decades.
