Study of Organic Carbon with Different Volatility
Vodička, Petr ; Schwarz, Jaroslav
This work characterizes diurnal trends of OC fractions at Prague suburban site during different seasons over the whole year. Moreover, owing to the parallel measurements at suburban site together with Czech background station Košetice during heating and non-heating season we found which OC fractions are typical for urban and rural environments and their diurnal trends.

Statistical Evaluation of New Particles Formation Events at Košetice Station
Zíková, Naděžda ; Ždímal, Vladimír
In this work, we present a basic statistical evaluation of NPF at Košetice background station in the region of middle Europe.Variability between the two years is not high, especially ratio of NPF events to all classifiable days varies only by several percents between the two years. Results from Košetice station are very similar to those from Hyytiala station (Finland), despite different geographical location and different time periods.

Chemical Composition of PM2.5 at Rural Backround Site Košetice
Schwarz, Jaroslav ; Havránek, Vladimír
PM2.5 generally represents fine fraction of atmospheric aerosol. Fine particles may remain in the atmosphere for days or even weeks and therefore they may be transported over long distances. Moreover, they may increase the background levels of atmospheric aerosol mass far from their origin. They have important adverse health effects and in the same time, they influence climate due to their direct and indirect effects on Earth radiative balance. To know the origin of PM2.5 aerosol, its chemical composition can serve as the diary of contacts with aerosol sources and transformations. Therefore it is necessary to study PM2.5 chemical composition if the fine aerosol sources should be revealed. A rural background site study can serve as a basis enabling to determine the real influence of larger sources like cities or an industry.
