Delhi’s air quality saw an improvement on Tuesday morning to settle in the ‘poor category’.

The Air Quality Index (AQI) in the city read 268 at 9.05 am. The AQI in Gurgaon and Greater Noida was recorded at 258 and 215 respectively. Neighbouring Faridabad (256) and Noida (247) also recorded their air quality in the poor category.

An AQI between zero and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”.

Delhi’s air quality was recorded in the “very poor” category on Monday.

The Ministry of Earth Sciences’ air quality monitoring agency SAFAR had said on Monday that a moderate wind speed is likely over the next two days and the minimum temperature is likely to drop in the national capital.

“The net effect is that the air quality will remain within the upper-end of the poor category or the lower-end of the very poor category,” it said.

The minimum temperature on Tuesday morning was recorded at 11.4 degrees Celsius, two notches above the season’s average.

The relative humidity at 8.30 am was at 80 percent.
