Abstract

Tethered-balloon borne observations show a correlation between a significant peak of ultrafine particle concentration and increased SO2 advected by a nocturnal low-level jet. The maximum of ultrafine particles is found at the lower edge of the jet in a region where the advected SO2 is mixed with colder and more humid air masses from below the jet. Model results corroborate that kinetic nucleation is the key mechanism for this nucleation event.
