2002 年 11 月 12 日，日本广泛观测到 Kosa 事件。2002 年秋季和初冬期间，在富山进行了按尺寸分离的气溶胶数量浓度和降水化学的测量。Kosa 事件期间，直径大于 3.0 mm 的气溶胶颗粒数量急剧增加，而更细颗粒的数量浓度几乎没有变化。科萨事件期间采样的降水中非海盐钙浓度和 pH 值较高。
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 m m 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.
