Abstract : Six different air masses that occur over twelve European cities are defined and discussed. The frequency of occurrence of the individual air masses over these cities over a period of several years was determined. The observations taken were reduced to monthly percentages. Continental polar and maritime polar were by far the most predominant air masses during the period of time studied. Continental polar was observed most frequently at seven of the cities and maritime polar most often at the other five cities, totaling 38 percent and 34 percent, respectively. The other four air masses combined only totaled 28 percent on an overall basis. The inland cities experience more continental polar air while the western cities nearer the sea coasts are dominated more by maritime polar air masses. Research related to maritime and continental aerosols and the influence of meteorological parameters upon aerosol particulates is described. (Author)
