A score of zero to fifty is good, 51 to one hundred satisfactory, 101 to 200 moderate, 201 to 300 poor, 301 to 400 extremely poor, and 401 to 500 severe.
Monday’s air quality in Delhi declined, but it was still classified as extremely poor because of the persistently bad effects of calm breezes on the dispersion of pollutants. At 10 a.m., the 24-hour average air quality index (AQI) was 337 (extremely poor), down from 325 (very poor) on Sunday.
The AQI was predicted to remain at a very poor level until November 2 and not enter the severe category. For the next six days, the air quality was probably in the extremely poor to poor range.
An AQI of zero to fifty is good, 51 to one 100 satisfactory, 101 to two hundred moderate, 201 to 300 poor, 301 to 400 very poor, and 401 to 500 severe.
After the wind shifted from northwest to southeast on Saturday, the AQI once more fell into the very poor range. While the alteration lessened the effects of stubble burning, it also caused the local wind speed to decrease.
Beginning on Saturday, the wind was blowing slowly and in a southeasterly direction. According to scientist Kuldeep Srivastava of the India Meteorological Department, “We expect wind direction to remain southeasterly until November 1.”
A minimum temperature of 16.2°C, which is normal for this time of the year, was recorded on Monday compared to 16.3°C on Sunday. It dropped to 14.3°C on Saturday.
