London Air Quality Network (LAQN)

Real-time and historical air pollution data from monitoring sites across London. Managed by Imperial College London. No auth required.

Data Model

  • Site — Monitoring station with @SiteCode (e.g. "MY1" = Marylebone Road), @SiteName, @SiteType (Roadside/Suburban/Urban Background/Kerbside), @LocalAuthorityName, and lat/lon coordinates.
  • Species — Pollutant type: NO2 (Nitrogen Dioxide), PM10, PM2.5, O3 (Ozone), SO2 (Sulphur Dioxide), CO (Carbon Monoxide). Each has health effect descriptions.
  • Readings — Hourly measurements with @MeasurementDateGMT and @Value (µg/m³). Empty @Value means no data for that hour.
  • Daily Index — Air Quality Index per site per day: 1-3 = Low, 4-6 = Moderate, 7-9 = High, 10 = Very High.

Key Site Codes

  • MY1 = Marylebone Road (busiest), KC1 = Kings College, WM6 = Westminster, BG1 = Barking

Gotchas

  • Response encoding has a UTF-8 BOM — always decode with utf-8-sig.
  • Endpoint paths use Information/ prefix for metadata queries.
  • All JSON field names start with @ (XML attribute convention).
  • Date format: YYYY-MM-DD in URL path segments.
  • Empty @Value strings indicate missing/unavailable readings.
