Abstract

Filter samples of atmospheric aerosol were collected daily at a city and a rural site over an extended period. The filters were processed in an environment supersaturated with respect to icein order to activate ice nuclei. The concentration of nuclei detected at the two sites was compared with reference to the local weather and air-mass trajectories. The city environment generally hasa larger ice nucleus concentration than the rural site. However, fluctuations in the concentrations at the two sites are usually in phase, indicating a pre-dominantly common origin. With air-mass trajectories over industrial regions, the nucleus concentration is increased. Local weather has a profound effect: in particular, rain and snow cause substantial reductions in ice nucleus concentration.
