Abstract Observations on the temporal dependence of the nephelometer scattering coefficient on relative humidity are presented and discussed for four different cases. For each case, the weather at the Research Triangle Park, North Carolina was dominated by an anticyclonic weather system. By taking simultaneous nephelometer scattering coefficient observation at two different relative humidities, it was possible to conclude that with nocturnal stable atmospheric conditions: In general, the scattering coefficient increases from sundown to sunup due to aerosol growth and an increasing trend of the aerosol number density: In general, the relatively rapid increase and subsequent decrease of the scattering coefficient during a 2 to 3 hour period after sunup is due to a relatively rapid aerosol growth and shrinkage. The latter behavior of the scattering coefficient was called an aerosol burst.
