High relative humidity due to light scattered rain led to secondary aerosol formation, causing spurt in particulate matter levels and air quality on November 3 was recorded in the severe+ category, the affidavit aid.

The Centre submitted that the Environment Ministry and the Central Pollution Control Board (CPCB) had been monitoring the air quality trends and also tracking actions to be taken by various government and private agencies.
