Continuous measurement of light scattering coefficient was made with an integrating nephelometer in the urban atmosphere of Nagoya for about two years, keeping the relative humidity of the air less than 50%. Monthly averaged light scattering coefficients in the season of autumn to early winter were present in high values more than 3×10-4 m-1 and they were measured in the cases of wind velocity less than 3.0 m/sec. The diurnal variation showed that a maximum value of light scattering coefficient was measured at about 12 LST in the summer, while the variations in autumn and winter had two maxima during the periods of 8 LST to 12 LST and of 17 LST to 22 LST. No systematic diurnal variation was found in the spring.
