Click/tap on the graph legend to show/hide pollutants. The graph starts with all measured pollutants visible, but this can make the graph a bit messy if there are several of them. Not all pollutants may have been recorded over the full time this monitoring station has been in operation. Note that the Air Quality Index is determined by the pollutant banding, not the absolute value, so the largest value on this graph may not be the most omportant pollutant. See How the Daily Air Quality Index is calculated for more information.
Current values at monitoring stations may not match today's forecast, because the forecast is an expected maximum whereas the current value is the most recent snapshot. Pollution levels typically peak in the afternoon or evening, and then drop overnight.
