It was an unusual September month this Monsoon season as the rainfall across the country was beyond expectation. But Delhi, unfortunately, was on the receiving end with rainfall in September ending on a deficient note.
However, one thing that went in favour of the city, and is something to cheer about was the controlled pollution levels. According to the pollution data available with Skymet, Delhi witnessed the cleanest September air in 9 years.
For a fact, both the PM2.5 and PM10 were within safe standards on an average. The PM10 level was seen to settle at 99 micrograms per cubic metre against the safe standard of 100. While PM2.5 level was 40 microgram per cubic metre which was well below the safe mark of 60.
The change in pollution levels has also proved to be extremely significant for the Air Quality Index started by the Central Pollution Control Board in 2015.
Fortunately, Delhi recorded no poor air days in September this Monsoon season. In fact, the city observed 19 days of satisfactory AQI, which means below the 100 mark. The remaining 11 days saw moderate air quality. This goes on to explain how good September was in terms of Delhiites getting some fresh air.
Below is a tale explaining the categories of air quality.
