UK Air Quality MCP Server

UK Air Quality (London Air / ERG)

Air quality data from the Environmental Research Group at Imperial College London, covering London boroughs, Hampshire, Essex, Sussex, Leicester, Cambridgeshire, and other UK regions.

Data Model

• Daily Air Quality Index — DAQI band 1-10 (1=Low, 4=Moderate, 7=High, 10=Very High) per site.
• Sites — Monitoring stations with type (Roadside, Urban Background, Suburban, Industrial, Kerbside).
• Species — Pollutants measured: NO2, PM10, PM25, O3, SO2, CO.
• Groups — Regional groupings: London, Hampshire, Essex, Sussex, Leicester, etc.

Key Patterns

• Use GroupName=London for London data, GroupName=All for all regions.
• Species codes: NO2 (Nitrogen Dioxide), PM10 (PM10 Particulate), PM25 (PM2.5), O3 (Ozone), SO2 (Sulphur Dioxide).
• Site types: Roadside, Urban Background, Suburban, Industrial, Kerbside, Rural.
• Dates in format YYYY-MM-DD or DD+Mon+YYYY (e.g. "01+Jan+2026").

Gotchas

• Response times: The API can be slow (5-10 seconds) for large date ranges.
• Data gaps: Not all sites measure all species; closed sites have @DateClosed set.
• XML-style JSON: Response fields are prefixed with @ (e.g. @SiteCode, @SpeciesCode).
• No pagination: Results are returned in full; use date ranges to limit data volume.
