Grid-to-Grid model estimates of daily mean river flow for gauged catchments in Great Britain (1891 to 2015): observed driving data [MaRIUS-G2G-Oudin-daily]

This dataset is a model output, from the Grid-to-Grid hydrological model driven by observed climate data (CEH-GEAR rainfall and Oudin temperature-based potential evaporation). It provides daily mean river flow (m3/s) for 260 catchments, for the period 1891 to 2015. The catchments correspond to locations of NRFA gauging stations (http://nrfa.ceh.ac.uk/). The data were produced as part of MaRIUS (Managing the Risks, Impacts and Uncertainties of drought and water Scarcity), which was a UK NERC-fund

What's in it

Data offered docs-verified: daily mean river flow (m3/s) · modelled daily flow for 260 NRFA gauged catchments
Coverage docs-verified: Great Britain (260 NRFA gauged catchments) · 1891-01-01 to 2015-12-30
Resolution docs-verified: Daily (temporal); point-based per gauged catchment (260 NRFA gauging station locations), not gridded
Formats docs-verified: CSV
Access docs-verified: Download from NERC EIDC; licence terms and conditions apply (Non-Open Government Licence per entry metadata); scripted download requires a personal access token (Bearer)

Useful for

Use cases llm-inferred: Long-run daily flow series (1891-2015) for FRA baseline flow context at NRFA gauged sites · Low-flow and drought frequency analysis for water resources assessments at gauged catchments · Benchmark or comparison series for calibrating or checking local hydrological models
Audience llm-inferred: hydrologists · flood consultants · water resources engineers · drought and water scarcity planners

Limitations

Constraints llm-inferred: Modelled estimates from the Grid-to-Grid model, not observed river flow · Only the 260 gauged catchment locations; no ungauged sites · Temporal extent ends 2015-12-30; no post-2015 data in this record · Licence terms apply and the dataset must be cited in any publication · Scripted download needs a personal access token · Record dates from 2018 (MaRIUS project 2014-2017); no update schedule stated
