Atmospheric aerosol concentrations were measured before and after rainfall at Fuchu City, Tokyo from June to November 1983. Before rainfall, the mean concentrations of total aerosol, (NO₃-N + NO₂-N) and SO₄-S were 193 μg•m^-3, 262 ng at•m^-3 and 8.7 μg•m^-3, respectively. And after rainfall, they decreased to 74 μg•m^-3, 117 ng at•m^-3 and 4.1 μg•m^-3, respectively. Before rainfall, aerosol concentration was higher when there was little wind, and it became nearly constant after rainfall. Therefore it is considered that decrease of aerosol depends on its concentration before rainfall. The amount of decrease of aerosol from atmosphere was not equivalent to the amount of chemical species precipitated by rainfall.
