Despite being the first working day of the week with a large number of vehicles on roads, values of primary pollutants were observed lower than their prescribed limits in several areas of the Capital.
The maximum temperature in February is four notches above normal while relatively high wind speed in North-West direction has resulted in the sudden fall of pollutants.

A senior Indian Metrological Department (IMD) official said wind is blowing with 15 km per hour speed in West-North-West direction. "As per the metrological sensors, wind speed and sunny weather both are responsible for settling down of mass concentration of Respirable Suspended Particulate Matter (RSPM)," said IMD official.
