Supplementary data to research paper "Frequency and area affected by critical rainfall conditions triggering debris flows increase in a changing climate"

Data description Climate data The climate data comprises observational and climate scenario data for rainfall events that potentially trigger torrent processes. Empirical intensity-duration relationships were established by integrating event data from the Austrian torrent event catalog with high-resolution, hourly re-analysis precipitation data. Critical rainfall conditions were identified for two primary process types: debris flow and fluvial. The data represents the number of precipitation events per year that exceed critical rainfall thresholds over a period of up to five consecutive days. An event is counted only the fist time it exceeds a critical threshold to prevent double-counting. The dataset includes one file for each process type for the observational data SPARTACUS, and one file for each process type and model for the Austrian climate scenarios ÖKS15. Resolution: Time: Annual Space: 1 x 1 km grid Domain: Austria Torrent data Torrent event data include the event date, process type, and triggering rainfall metrics (total event precipitation, rainfall duration, rainfall intensity, maximum intensity, antecedent precipitation for 1, 3, 7 and 28 days), mapped to the catchment centroids. The data source denotes the WLK database (source = 1), supplemented with events from ERDOK (source = 2), respectively.
