To identify these events, we employed the Standardized Precipitation Index (SPI) at a 12-month timescale. Drought events were identified as periods of at least three months where significantly dry conditions affected 20% or more of the study area, defined as grid cells with SPI values lower than −0.84. Our analysis revealed a total of 40 major drought events. Our catalogue contains detailed information on each episode’s spatial extent, duration, severity, and spatio-temporal dynamics. The analysis of the propagation patterns of the events unveils substantial heterogeneity, implying that droughts stem from diverse atmospheric mechanisms, further influenced by complex local topography. The open-licensed drought database serves as a valuable resource. It not only facilitates exploration of drought onset and evolution mechanisms but also aids in assessing drought impact on agricultural and other socio-economic sectors. info:eu-repo/grantAgreement/ES/DGA/E02-23R info:eu-repo/grantAgreement/ES/MICINN/CGL2017-83866-C1-3-R info:eu-repo/grantAgreement/ES/MICINN/CGL2017-83866-C3-3-R info:eu-repo/grantAgreement/ES/MICINN/PID2020-116860RB-C22 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 6.9 2024 MULTIDISCIPLINARY SCIENCES 15 / 136 = 0.11 2024 Q1 T1 1.867 2024 Computer Science Applications 2024 Q1 Education 2024 Q1 Statistics, Probability and Uncertainty 2024 Q1 Library and Information Sciences 2024 Q1 Statistics and Probability 2024 Q1 Information Systems 2024 Q1 8.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Beguería, Santiago (orcid)0000-0002-3974-2947 Vicente-Serrano, Sergio M.
