Urban and Suburban Intermodal Fraction of Atmospheric Aerosol in Winter 2014
Kozáková, Jana ; Hovorka, J. ; Schwarz, Jaroslav
Fine (PM1) and coarse (PM10-2.5) aerosols differ not only in size but also in the chemical composition, health effects, type of sources, and others. A dividing line between fine and coarse aerosol is not clearly defined. These fractions overlap in the aerodynamic particle size range 1-2.5 μm, also called the intermodal fraction. Sources of both coarse and fine aerosols contribute to the intermodal fraction to a different extent relating to different meteorological conditions and types of locations. According to several studies, the intermodal fraction highly correlated with coarse aerosol in dry areas during high wind speed episodes. In contrast, other studies have shown higher or comparable correlation with fine aerosol. The aim of this study is to characterize the intermodal fraction in urban and suburban localities and estimate to what extent fine/coarse aerosol sources contribute to this fraction.

SMPS Spectra Dependence on Air Masses Origin at Košetice Station
Zíková, Naděžda ; Ždímal, Vladimír
The varibility in atmospheric aerosol (AA) concentrations is considerable even at rural background stations with suppressed direct anthropogenic influence (Zíková & Ždímal, 2013), and strongly depends, among other meteorological parameters, on wind speed and direction. The wind direction, however, gives only limited information on the air masses origin, so the more detailed analysis of air mass trajectories was done to describe the variability of the AA at the Košetice station.
