1. The index will not only give people an idea of the air quality, but also the corresponding health impacts they are likely to face.
2. The index could also help rank how each city is doing in terms of air quality.
3. AQI is a method by which individual air pollution parameters of each pollutant can be translated into a single number or a set of numbers.
4. For instance, an AQI of 301-400 denotes "very poor" quality and the corresponding PM 2.5 concentrations are 121-250 microgram per cubic metre.
5. The scheme may initially kick off in 16 cities, which have automatic air quality monitoring stations. The rest may take longer.
