[EN] The dataset is comprised of 48 NetCDF files, each representing a distinct temporal scale spanning from 1 to 48 months. It can be accessed and manipulated using various software tools, including GIS applications like QGIS and ArcMap, specialized applications like Panoply (https://www.giss.nasa.gov/tools/panoply/), and dedicated libraries such as ncdf4, raster, or terra in R, as well as netCDF4 or xarray in Python, among others. Each NetCDF file contains a 3-dimensional matrix with dimensions of 720x360x1476. Land pixels are marked with the value 1.0x10^30, and occasionally, calculation errors may lead to NaN values. The dataset has been generated in R using the SPEI package (http://cran.r-project.org/web/packages/SPEI).

[ES] La base de datos SPEI (SPEIbase) ofrece un registro global completo de las condiciones de sequía. Proporciona una medida estandarizada de la sequía, el Índice Estandarizado de Precipitación-Evapotranspiración (SPEI), calculado a múltiples escalas temporales que van desde un mes hasta 48 meses. El índice SPEI considera tanto la precipitación como la evapotranspiración potencial (ETP), estimada utilizando el método FAO-56 Penman-Monteith. Este enfoque proporciona una evaluación sólida y precisa de las condiciones de sequía en diversas regiones y periodos de tiempo. SPEIbase es de libre acceso y se puede utilizar para respaldar una amplia gama de aplicaciones, incluido el monitoreo de sequías, la evaluación de riesgos y los estudios sobre el cambio climático. Esta es una actualización de la versión SPEIbase v2.8 (https://digital.csic.es/handle/10261/288226) basada en el conjunto de datos CRU TS 4.07, que abarca el período comprendido entre enero de 1901 y diciembre de 2022. Para obtener más información sobre la base de datos SPEIbase, consulte: https://spei.csic.es/
[EN] The SPEI database (SPEIbase) provides a comprehensive global record of drought conditions. It offers a standardized measure of drought, the Standardized Precipitation-Evapotranspiration Index (SPEI), computed at multiple time scales ranging from monthly to 48 months. The SPEI index considers both precipitation and potential evapotranspiration (PET), estimated using the FAO-56 Penman-Monteith method. This approach provides a robust and accurate assessment of drought conditions across various regions and timeframes. SPEIbase is freely accessible and can be used to support a wide range of applications, including drought monitoring, risk assessment, and climate change studies. This is an update of the SPEIbase v2.8 (https://digital.csic.es/handle/10261/288226).-- What’s new in version 2.9: 1) Based on the CRU TS 4.07 dataset, spanning the period between January 1901 to December 2022.
