What is AQI and how is it different from PM2.5?

AQI (Air Quality Index) is a single number calculated from several pollutants: PM2.5, PM10, ozone, carbon monoxide, nitrogen dioxide and sulphur dioxide. The pollutant with the worst value in that hour sets the AQI. The Pollution Control Department's bands are 0 to 25 excellent, 26 to 50 good, 51 to 100 moderate, 101 to 200 unhealthy for sensitive groups and 201 and above unhealthy. PM2.5 is one pollutant only: the concentration of particles up to 2.5 microns across, measured in µg/m³. This site uses PM2.5 as its main value and for card colours, and shows AQI as supporting data, so the two can fall in different bands.
