UK-AIR station DAQI
For a location in the United Kingdom, OpenMapX can use the nearest UK-AIR monitor's official current DAQI when that monitor is within 25 km. The value is the agency's published station index from 1 to 10. The evidence includes the station name, distance, observation time, freshness, source, licence, and methodology.
Station conditions may differ from the requested location, especially near roads, industrial sites, terrain changes, or local weather. The result is labelled preliminary and should be used with the linked official guidance.
