Delhi-NCR woke up to a dense foggy morning on Sunday and the air quality levels were recorded in the poor category, according to the Central Pollution Control Board (CPCB) data. There was near-zero visibility and several train and flight operations were affected because of this. The minimum temperature settled at 9.4 degrees Celsius, a notch above the season's average. The maximum temperature was forecast to be 19 degrees Celsius, normal for this time of the year, a meteorological department official said.
On Sunday, the pollution level was recorded in the 'very poor' category after light rains slowed dispersion of pollutants and worsened the pollution situation in the national capital.
Major pollutants PM 2.5 at 222 and PM 10 at 229, both in 'Poor' category in Lodhi Road area, according to the Air Quality Index (AQI) data.

In the National Capital Region, Ghaziabad, Faridabad, Greater Noida and Noida recorded 'very poor' air quality while Gurgaon, recorded 'poor' air quality, the CPCB data showed.
"This is a typical scenario when a little shower becomes a stumbling block for dispersion of pollutants in spite of not-so-calm surface wind conditions, by introducing a huge amount of moisture to make air heavy with drops in temperature, a situation that causes difficulty for dispersion. this process is balancing the air pollution level and keeping it consistently in the lower end of very poor range," the Centre-run System of Air Quality and Weather Forecasting (SAFAR) said.
