High-resolution multi-drought indices across Austria for the 1950 - 2023 period

This dataset offers a comprehensive, long-term overview of multiple drought indices for Austria, spanning from 1950 to 2023. It includes six well-established drought indices: the Reconnaissance Drought Index (RDI), the modified Reconnaissance Drought Index (RDIe), the Standardised Precipitation-Evapotranspiration Index (SPEI), the Standardised Precipitation Index (SPI), the Vapour Pressure Deficit (VPD), and the self-calibrating Palmer Drought Severity Index (scPDSI). These indices are calculated monthly using Reanalysis ERA5-Land data, which has a horizontal resolution of 0.1°. Additionally, the SPI is calculated monthly from 1950 to 2014 using the HISTALP dataset, which has a higher resolution of 5 minutes of a degree. The input parameters consist of total precipitation from both the HISTALP and ERA5-Land datasets, along with potential evapotranspiration derived from variables within the ERA5-Land data. The dataset encompasses multiscale indices that cover various timescales, ranging from 1 to 48 months. This provides a thorough perspective on hydroclimatic variability and represents different types of drought, including meteorological, agricultural, and hydrological. The data is available in several formats (.nc, .csv, and .xlsx), facilitating flexible spatial and temporal analyses.
