A range of instrumentation across 6 AWS sites and 10 gauging stations delivered meteorological and river flow data from 1968 to 2010 to explore changing hydrometeorology as part of the long-term Plynlimon catchment monitoring study.\nThe dataset includes: air temperature, temperature depression, Vapour Pressure Deficit (VPD), precipitation, solar radiation, net radiation, wind speed, wind direction, and river flow.","metadataDate":"2025-12-16T09:43:39","resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/a815235d-6ae1-4e5a-b5cd-138455607cd1"},{"code":"10.5285/a815235d-6ae1-4e5a-b5cd-138455607cd1","codeSpace":"doi:"}],"relationships":[{"relation":"https://vocabs.ceh.ac.uk/eidc#memberOf","target":"91961a0f-3158-4d00-984d-91eb1e03e8bd"}],"lineage":"Raw measurements are provided along with derived, quality controlled (QC'd), aggregated, and gap-filled data.\nThe supporting document provides collated and QC'd information on this dataset.
