This dataset is a model output from the European Monitoring and Evaluation Programme (EMEP) model applied to the UK (EMEP4UK) driven by Weather and Research Forecast model meteorology (WRF). It provides daily mean atmospheric compositions and fluxes of the UK on a 3x3 km2 resolution grid for years between 1960 and 2020. The EMEP4UK model version used here is rv5.0, and the WRF model version is the 4.4.2. This work was supported by the Natural Environment Research Council award number NERC (NE/R016429/1) as part of the UK-SCAPE programme delivering National Capability.
