Indicative data generated for Breathe London devices
(Note: anomalies are likely to occur if an insufficient amount of data has been generated, especially for "Weekends & Public Holidays".)

The following charts are provided to help contrast indicative concentrations reported for the Breathe London Piccadilly Circus node with those at Cat Hill Allotments and the National Gallery (neaby), and the reference monitor at Waterloo Place (even closer, about 100 metres away).
