The distribution of pollutants near a frontal surface: A comparison between field experiment and modeling

Abstract

A number of frontal systems passed through the experimental area during the 1984 North Bay Acid Snow Study. Two different cold frontal systems were examined using aircraft instrumented for cloud and air chemistry, and cloud microphysics measurements. A distinct maximum in aerosol particle number concentration was detected near both frontal surfaces. In at least one case, a peak in NOx concentrations was observed simultaneously with the aerosol particle maximum. Using a model of frontogenesis, the aerosol particle layer can be explained in terms of air circulations associated with a front. The model also demonstrates how better flight plans might be designed for air chemistry studies using aircraft.
