For the city of Delhi, an air quality index methodology was proposed and applied for six criteria pollutants - PM10, PM2.5, CO, NOx, SO2, and Ozone and analyzed for trends in the past three years of data. The AQI is reported on a scale of 0 to 500 and subdivided into six colored bins for easy understanding of the common person and the media.
