A factory emits 70 g/s of NO2 from an effective stack height of 40 m. The wind speed is 5.5 m/s and it's a cloudy night. There is an atmospheric inversion at an elevation of 100 m.

A)Estimate the ground level NO2 (ug/m^3) at a point 8 km directly downwind of the factory

B)Esitmate the ground level NO2(ug/m^3) at a point 8 km directly downwind of the factory, if there was no inversion.
