What's the Data Saying?

According to the Central Pollution Control Board, in 2023, Delhi inhabitants enjoyed a clear sky and ample sunlight on Diwali, with an AQI of 218, compared to 312 in 2022, 382 in 2021, 414 in 2020, 337 in 2019, 281 in 2018, 319 in 2017, and 431 in 2016.

As per the data, the pollutant PM2.5 level was recorded at 145 micrograms per cubic meter at 3 PM.
