Title: What is the connection between atmospheric aerosols, meteorological pa- rameters and gaseous pollutants? Author: RNDr. Naděžda Slezáčková Zíková Department: Department of Meteorology and Environment Protection Supervisor: Ing. Vladimír Ždímal, Dr. Laboratory of Aerosol Chemistry and Physics, Institute of Chemical Process Fun- damentals, Czech Academy of Sciences, v.v.i. Abstract: Five years of atmospheric aerosol (AA) measurements at rural back- ground station Košetice were compared with meteorological records and gaseous pollutants concentrations. The sampling and data analysis of AA data is de- scribed, and the statistical evaluation is done. The variability in the AA con- centrations is significant; the long-term measurements of AA, over the period at least several years, and the differentiation according to the season of the year are thus necessary. The clearly expressed annual cycle of AA concentrations is mainly influenced by two phenomena. From April to September, the total AA concentration cycle is driven mainly by the new particles formation events, from October to March, the concentrations are strongly influenced by particles coming from long-range transport and/or from the regional pollution. The relationship between AA and meteorological parameters, however, is not only season...

Air Quality in Different Types of Archives
Mašková, Ludmila ; Smolík, Jiří ; Ondráček, Jakub
Particulate matter (PM) and gaseous pollutants in libraries and archives can be harmful for materials stored there. The study includes indoor/outdoor monitoring of air quality in 4 archives, which representing different outdoor environments: Zlatá Koruna (rural), Třeboň (small city), Teplice (industrial area), and Prague (large city with traffic). The aim of this study is to investigate concentrations and sources of airborne PM and gaseous pollutants in the indoor environment of the archives, and to establish the relationship between the indoor and outdoor environment. The results indicated outdoor air as the most probable source of particles in the indoor environment of naturally ventilated archives at Zlatá Koruna, Třeboň and Teplice. The concentrations in the indoor environment in Prague are relatively constant and low, because the archive is equipped with a sophisticated filtration systém.

Air Quality in the Indoor Environment of Libraries and Archives
Mašková, Ludmila ; Smolík, Jiří
The aim of this study is to investigate concentrations and sources of airborne PM and gaseous pollutants in the indoor environment of the archives, and to establish the relationship between the indoor and outdoor environment. In 2012 the measurements take place at Zlatá Koruna and Třeboň and in 2013 at Osek and Prague. The results indicated outdoor air as the most probable source of particles in the indoor environment of archives at Zlatá Koruna and Třeboň. The penetration of particles at Třeboň was higher than at Zlatá Koruna. These results were confirmed by measurements of ventilation rate, which was at Třeboň almost ten times higher than at Zlatá Koruna.

Connection between Atmospheric Aerosol, Gaseous Pollutants Concentrations and Atmospheric Stability Parameters
Zíková, Naděžda
This work attempts to find suitable criteria to asses an atmospheric stability in order to estimate relationships between aerosol particles concentration, meteorological conditions and concentrations of gaseous pollutants (ozone, NO2 and SO2). Searching of the connection is based on meteorological data and concentrations of gaseous pollutants monitored by the CHMI, and data measured by the Laboratory of Aerosol Chemistry and Physics. An aerological method, a synoptical method and CAPE and MOCON values are applied to the data acquired at the station Bílý Kříž during an experimental campaign. Aerological method and CAPE are the most suitable ones. Synoptical method shows mainly origin of air masses instead of its stability and MOCON does not seem to have any expressive influence on particles’ and gaseous pollutants’ concentrations.
