Abstract
The Kosa event was observed widely in Japan on 12 November 2002. Measurements of size-separated aerosol number concentrations and precipitation chemistry were performed in Toyama during the autumn and early winter of 2002. The number of aerosol particles larger than 3.0 μm in diameter dramatically increased during the Kosa event, whereas the number concentrations of finer particles hardly changed. The concentration of non-sea-salt calcium and pH were high in the precipitation sampled during the Kosa event.
