According to the Central Pollution Control Board (CPCB) recordings, Delhi’s overall air quality index (AQI) settled at 278 on Wednesday.

The average PM 10 levels in Delhi on Tuesday rose from 252ug/m3 at 7am to 300ug/m3 at 1pm, before it finally started reducing to reach 293.2ug/m3 at 5pm.

A senior scientist at IMD said that Delhi on Tuesday received easterly winds with a speed of 6-8kmph. “Around afternoon for some time, the wind speed improved a little because of which the air quality managed to remain in the poor zone and not slip to the very poor zone. The situation will be similar on Wednesday and Thursday, there is no significant improvement. From October 16, we are expecting that the air quality will start improving,” the scientist said.
