Further information and help »

This dataset includes gridded daily averaged atmospheric composition for the UK for key air pollutants nitrogen, sulphur, particulates and ozone for the years 2000, 2015 and 2022. The dataset was generated with the European Monitoring and Evaluation Programme for the UK (EMEP4UK) model version 5.0, modified to improve wet deposition rates. The underlying meteorology was generated using the Weather Research and Forecasting (WRF) model version 4.4.2.
These model outputs were generated as part of the National Capability for UK Challenges (NC-UK) programme, funded by the UK Natural Environment Research Council (NERC), and the National Focal Centre (NFC) work on Mapping and Modelling Critical Loads and Critical Levels, funded by the UK Department for Environment, Food & Rural Affairs (Defra).

Provenance & quality

Daily average concentrations for a model domain covering the UK with a grid resolution of about 3 km x 3 km were calculated using the EMEP4UK atmospheric chemistry transport model. The model was evaluated using the UK Automatic Urban and Rural Network (AURN) monitoring stations. R was used to access the AURN dataset to evaluate the EMEP4UK model output.

Key input data to the EMEP4UK model include:
- anthropogenic emissions for the UK from the National Atmospheric Emissions Inventory;
- anthropogenic emissions for the Republic of Ireland from MapEire;
- anthropogenic emissions for Europe from the Centre for Emissions Inventories and Projections;
- UK land surface data from the Land Cover Map 2015; and
- European land cover data and other default EMEP model inputs from the EMEP repository.

The data were processed from the full EMEP4UK model output to a subset containing essential variables only. The netCDF Operators tools, version 5.3.3, were used to subset the model output.
