Caravan-Qual is an open access dataset that brings water quality to the research paradigm of large sample hydrology (LSH), integrating daily water quality data from 100 constituents with catchment attributes, meteorological forcing and co-located streamflow observations. Water quality data in Caravan-Qual is compiled from several existing global, regional and national databases, all of which have fully open-access licenses that permit redistribution, including: • Global: UNEP GEMS/Water Global Freshwater Quality Archive (GEMS) • Global: Global River Water Quality Archive (GRQA) • Global: GLObal River Chemistry (GLORICH) dataset • Europe: NORMAN EMPODAT • Europe: Waterbase WISE State of Environment (Waterbase) • United States: Water Quality Portal (WQP) • China: China National Environmental Monitoring Centre (CNEMC) • United Kingdom: Department for Environment, Food and Rural Affairs (UK-EA) • Canada: Canadian Environmental Sustainability Indicators (CESI) • Switzerland: National Surface Water Quality Monitoring Programme (NAWA) Where possible, water quality monitoring observations are matched to publicly accessible streamflow observations (Caravan + extensions), and stream attributes (GEOGLOWSv2), catchment attributes (HydroATLAS) and climate data (ERA5-Land) are derived.
