| Zusammenfassung |
| Siberia is of great importance to understand the climate change due to it covers about 10% of
Earth’s land surface and it has the largest area to be studied under the Pan-Eurasian
Experiment (PEEX). In the overview done by Kulmala et al. (2011) authors arrived at a
conclusion that continuous and comprehensive measurements of GHGs and aerosols over
Siberia are still lacking. Understanding the importance of this problem, in recent
years the Institute of Atmospheric Optics SB RAS established several monitoring
stations for continuous measurements of aerosol and trace gas species to fill up this
gap.
In this paper we present some results of continuous measurements of trace gas species
and aerosols carried out at three stations located in West Siberia. The first one is a so-called
TOR-station located in the scientific campus of Tomsk (56°28’41"N, 85°03’15"E), the
second one is the Base Experimental Complex (BEC, 56°28’49"N, 85°06’08"E) – in the
eastern suburbs of Tomsk, and the third one is Fonovaya Observatory (56°25’07"N, 84Ë
04’27"E) – in a rural area 60 km west of Tomsk. All equipment of the stations is fully
automated and can be monitored via Internet. Gas analyzers are hourly calibrated against
standard gas mixtures, micro-flux gas sources, or gas generators, depending on the instrument
type and the gas to be detected.
Aerosol measurements carried out continuously from March 2010 enabled a frequency
and seasonal dependency of the new particle formation (NPF) events to be revealed. NPF
events in Siberia are more often observed during spring (from March to May) and early
autumn (secondary frequency peak in September). On average, NPF evens took place on
23-28 % of all days.
