Abstract :
In the present study, atmospheric carrying capacity was estimated based on ventilation
coefficient. Ventilation coefficient is directly proportional to the atmospheric carrying capacity that
was computed by using micrometeorological parameters of two seasons namely winter and summer.
The diurnal variation in ventilation coefficient was recorded. The highest value of air carrying
capacity was observed during the afternoon hours and it decreases in morning and evening hours in
both the seasons. It was noticed that the winter season has low air carrying capacity throughout the
day as compared to summer. The value of ventilation coefficient was observed to be less than 2000
2 m /s during morning and evening hours in winter. Whereas, higher ventilation coefficient value
2 lower than 8000 m /s was recorded during the summer season.
