Rainfall provides the major hydrological input into a catchment. The National River Flow Archive provides catchment rainfall time series and statistics to assist in the analysis and understanding of river flow data. The principal NRFA catchment rainfall information is the monthly catchment rainfall series.
Other Sources of Rainfall Data and Other Meteorological / Climatological Data
If users require rainfall information other than that held by the NRFA. The following external sources of rainfall and other meteorological/climatological data may be useful:
Met Office: The UK’s National Weather Service
UK Hydrometric Measuring Authorities: As well as river flow monitoring, many of the UK hydrometric measuring authorities operate other hydrometerological monitoring networks.
British Atmospheric Data Centre (BADC): The Natural Environment Research Council's (NERC) Designated Data Centre for the Atmospheric Sciences
