Figures are hourly values from the Open-Meteo Air Quality API, modelled from Copernicus CAMS forecasts for the city-centre coordinates rather than read from a single ground station. Concentrations are in micrograms per cubic metre; the US AQI follows EPA breakpoints and reports the worst pollutant. Data is cached for 15 minutes.
