High concentration of air pollutants like nitrogen oxides found in an urban area during the nighttime was shown to be closely related to urban boundary layer (UBL) heights and wind speed. The UBL heights were estimated from continuous measure ments of aerosol profiles with a Mie lidar. Since the aerosol profiles reflect the structures of UBL, they can be used to infer the heights of UBL. When defining a stagnant factor as an average of the reciprocal of the product between the height of UBL and the wind speed, the nighttime averages of nitrogen oxide and nitrogen dioxide were shown to be linearly proportional to the stagnant factor.
