Though still a matter of concern, the air quality in the national capital in November had improved than before to make it slightly better than the last year’s. According to reports from the Delhi Pollution Control Committee’s (DPCC) R K Puram air quality monitoring station, the number of days with severe air pollution this year had reduced to 11 compared to the 12 days last year. However, number of days with moderate air pollution are three this year while last year there were none.

DPCC data also suggests that the concentration of Particulate Matter (PM) 2.5 and 10 were also being measured less than the last year. Scientists at DPCC credited wind speed for the drop in pollution, this year, citing that the wind speed was 0.4 meters/second, during daytime in the first week while it rose to about 1.2 meters/second post Diwali.

Apart from the wind speed experts had also pointed the government’s measures to improve air quality, announced on November 6, to be one of the vital reason for the decrease in pollution this year.

Earlier in the month of November, dense pollutants, including dust and smoke had blanketed the city with dense smog resulting in low visibility through the day. The capital city had been facing air pollution at its worst ever, with the Air Quality Index (AQI) on Sunday at 497, even worse than the post-Diwali AQI, which was 445. The Central Pollution Control Board had cited the variable pattern of the wind for the highest concentration of dust accumulated in the city.
