Delhi’s air quality ‘poor’ again, Met predicts a partly cloudy day as mercury drops marginally

Delhi’s AQI climbed to a poor 274 at 8.30am, from Monday’s 24-hour average of 234. Sunday’s promise of respite, when the AQI had dropped to a moderate 197, seems to have been short lived.

Tuesday morning in Delhi saw the mercury level drop and air quality index rise with the Met department predicting a partly cloudy sky during the day.

Pollution levels rose again in the national capital with the AQI — a measure of pollutants in the air — climbing to a poor 274 (on a scale of 500) at 8.30am, from Monday’s 24-hour average of 234. Sunday’s promise of respite, when the AQI had dropped to a moderate 197, seems to have been short lived.

Areas close to Anand Vihar were the most polluted with an AQI of 356, categorised as very poor. The primary pollutant here was the finer and more dangerous particulate matter PM 2.5.

The Delhi Technical University, ITO, RK Puram, Siri Fort, Punjabi Bagh, and Netaji Subhash Institute of Technology in Dwarka, also had very poor air according to the data collated by the Central Pollution Control Board (CPCB).

With an AQI of 177, Pusa road and adjacent areas, breathed the cleanest air in Delhi. Dilshad Garden and the North Campus also had moderate quality air.

Morning temperature dropped from Monday’s 9.8 degrees to 9.6 degrees on Tuesday. This may rise up to 25 degrees Celsius during the day. The city also saw winds from the west blowing at the speed of 5 kmph.

Temperatures could rise further in the city as the north-westerly winds — which usually route from colder Jammu and Kashmir regions before hitting Delhi — have changed direction and are now blowing over Punjab and Pakistan before reaching Delhi.

By Friday, the MeT department expects minimum and maximum temperature to rise up to 12 and 25 degrees Celsius respectively.
