Winds from north bring chill to the city, air quality better

The national Capital breathed better on Wednesday, with the air quality improving significantly after light rains hit the city a day before. The air quality index (AQI) improved to 270, against Tuesday’s 290. 

Scientists at the Central Pollution Control Board (CPCB) attributed the better air quality to the rain and picking up of wind speed. 

The day temperature fell to 21.3 degrees Celsius, with cold winds coming from northern India. On Tuesday, the temperature was recorded at 21.7 degrees Celsius. 

The rain, which continued through Monday night, also brought down the temperature in Delhi-NCR. Just a day later, however, the AQI again plummeted to ‘very poor’. The AQI in Ghaziabad rose to 359 units while in Noida, it shot up to 264. At Faridabad, however, air quality remained ‘moderate’ at 190 units.

The AQI units are measured against PM 2.5, the most prominent pollutant in Delhi -NCR (measured in microgram per cubic meters).
