Delhi’s Air Quality Index (AQI) is a measure of the air quality in the city, and it enters the ‘Poor’ zone when the levels of pollutants in the air exceed certain limits. However, the evidence provided does not explain how the AQI works in detail.
The evidence mentions that Delhi AQI has entered the ‘Poor’ zone, but it does not provide information on the specific parameters or mechanisms involved in calculating the AQI. It also mentions a Winter Pollution Plan and the possibility of work-from-home arrangements being considered, but these are separate topics and do not provide insight into how the AQI works.
The evidence does not provide a detailed explanation of the AQI’s functioning, so it is not possible to provide a comprehensive answer to the question of how the AQI Delhi today works.
