AQI Delhi, or Air Quality Index Delhi, is a measure of the level of air pollution in the city. It works by tracking the concentration of pollutants such as particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO) in the air.
The AQI Delhi is calculated based on the concentration of these pollutants and is categorized into different levels, ranging from good to severe. The levels are as follows: good (0-50), satisfactory (51-100), moderately polluted (101-200), poor (201-300), very poor (301-400), and severe (401-500).
The article from India Today explains that Delhi’s 45-degree heat and poor AQI are connected, as the heat wave leads to an increase in pollution levels. However, the article does not provide detailed information on how the AQI Delhi is calculated. It only mentions that the heat wave contributes to the poor air quality in the city.
