This dataset includes daily averaged atmospheric composition for the UK for key air pollutants nitrogen, sulphur, particulates and ozone for the years 2022 - 2024. 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. The UK emissions were taken from the 2025 release of the National Atmospheric Emissions Inventory (NAEI), with base year 2023.
