Field notes
The page explains that each map dot represents a monitoring station and that darker colour signals worse air, even within the same index band. It distinguishes the short-term daily score from last year’s average, noting that low daily readings do not establish that air meets annual health guidelines. The page also names the London Air Quality Network at Imperial College London as its live-data source.
