Hydrologic and meteorologic extremes and transitions for 4299 catchments in Europe

This dataset provides the data needed to reproduce the results by Brunner et al. 2025, ERL: 'Meteorological and hydrological dry-to-wet transition events are only weakly related over European catchments'. Namely, catchment shapefiles and attributes of 4299 catchments in Europe and extracted hydrologic (floods/droughts) and meteorologic extreme events (wet and dry spells) as well as their transitions.
It relies on a large-sample dataset of daily hydrological observations and catchment shapefiles compiled for 24 countries in Europe by collecting data from national agencies and existing large-sample datasets including the Global Runoff Database (GRDC, 2019), EStreams (Nascimento et al. 2024), and two datasets from the Catchment Attributes and Meteorology for Large-sample Studies (CAMELS; Addor et al. 2017) suite, namely, CAMELS-CH (Höge et al. 2023) and CAMELS-DE (Loritz et al. 2024) (see Table 1 in the Supplementary Information for an overview and data sources).
