Experts attributed the dip to a change in the wind direction, which led to a higher contribution of stubble burning as well

Data shows the contribution of stubble burning to Delhi’s air pollution had increased from 1.6% on Friday to 9.03% on Saturday.

This October seemed to promise clean air, with the average air quality index (AQI) remaining below 200 (moderate) in the city. But with most monitoring stations going dark throughout the month, a true picture of AQI is guesswork. Gurgaon ended Oct with an AQI of 195 on Friday. At first glance, this might appear to be an improvement, but Gurgaon saw a decline in air quality going by the data.

The city’s air quality index (AQI), which Thursday had plunged to its worst October level in three years at 373, unexpectedly improved Friday to 218 — a drop of 155 points.

Delhi's air quality dramatically improved, dropping from a three-year October high to 'moderate' levels. This significant shift, without rain, has experts puzzled. The government credits extensive enforcement teams, anti-smog guns, and road sweeping. While meteorological factors like lower humidity and wind shifts played a role, the full reasons for this sudden improvement remain under investigation.
