UK Air Quality Reanalysis (AQREAN): Bias Corrected Surface Level
Abstract
The UK Air Quality Reanalysis (AQREAN) combines an air quality forecast model with a bias-correction post-processing system, incorporating ground-based pollutant observations, to give an improved estimate of pollutant levels for the UK.
The data covers the UK at the surface level on a 0.1degree horizontal grid, at hourly time resolution.
This dataset contains the following species:
• Particulate matter, with diameter < 2.5 µm (PM2.5)
• Particulate matter, with diameter < 10 µm (PM10)
• Ozone (O3)
• Nitrogen Monoxide (NO)
• Nitrogen Dioxide (NO2)
• Sulphur Dioxide (SO2)
• Carbon Monoxide (CO)
The Daily Air Quality Index (DAQI) is also included, along with the species-specific DAQI for the contributing pollutants.
Note:
• AQREAN is only representative of ambient background pollutant concentrations.
• Data is masked to include only land-based locations as no observations are included to support the bias corrections over the ocean.

| Title | AQUM: Air Quality in the Unified Model deployed on unknown computer |
| Abstract | This computation involved: AQUM: Air Quality in the Unified Model. The on-line air quality model AQUM (Air Quality in the Unified Model) is a limited-area forecast configuration of the Met Office Unified Model which uses the UKCA (UK Chemistry and Aerosols) sub-model. AQUM has been developed with two aims: as an operational system to deliver regional air quality forecasts and as a modelling system to conduct air quality studies to inform policy decisions on emissions controls.
