EMEP4UK: Daily UK Air Pollution Grids for 2000, 2015, and 2022

Gridded daily averaged atmospheric composition for the United Kingdom for key air pollutants including nitrogen, sulphur, particulates, and ozone. 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. It was produced as part of UK research council and government-funded programs.

Use Cases

• Analyzing long-term trends in air pollutant concentrations based on the provided years 2000, 2015, and 2022.
• Modeling pollutant deposition fluxes based on the improved wet deposition rates mentioned in the description.
• Assessing compliance with air quality standards using gridded daily concentration data.
• Studying the impact of meteorology on pollution dispersion using the underlying Weather Research and Forecasting (WRF) model outputs.

Strengths

• Covers three distinct years (2000, 2015, 2022) enabling temporal trend analysis.
• Includes multiple key pollutant types: nitrogen, sulphur, particulates, and ozone.
• Uses a scientifically recognized model (EMEP4UK v5.0) with modifications for improved wet deposition.
• Funded by authoritative UK bodies (NERC and Defra), suggesting a research-grade origin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the model and selected years.
