Summary:
The moderate fog is likely to bring down the inversion layer to keep both gaseous and particulate pollutants near the surface unless sufficient rain occurs. If there is not enough rain, it will only increase the pollution levels as the moisture will aid in trapping pollutants,” a CPCB official said. “The rain needs to be sufficient if the pollution has to go down. Calm surface winds are not allowing pollutants to disperse. “There will be shallow to moderate fog in the morning with a possibility of rain later,” said an official.At 7.6 degrees Celsius, Delhi had recorded its coldest day of the season so far on Saturday..
