This dataset provides hydrometeorological time series and landscape attributes for 671 catchments in the UK. It collates river flows, catchment attributes and catchment boundaries from the UK National River Flow Archive and a new set of meteorological time series and catchment attributes. Daily time series of a range of hydrometeorological data (including rainfall, potential evapotranspiration, temperature, radiation, humidity and flow) are provided for the period 1 October 1970 to 30 September 2015. A comprehensive set of catchment attributes are quantified, describing a range of catchment characteristics including topography, climate, hydrology, land cover, soils, hydrogeology, human impacts and emission uncertainty.

The dataset is intended to be used by the community as a free, easily accessible dataset for a wide range of environmental data and modelling analyses. A research paper describing the dataset in detail (Coxon et al., CAMELS-GB: Hydrometeorological time series and landscape attributes for 671 catchments in the UK) will be made available at Earth System Science Data (https://www.earth-system-science-data.net/).

The dataset was released on February 20, 2020.
