Conclusion
[24] Practically all sources and sinks have a seasonal pattern. Seasonal variations of VOC connected with the
biological activity of trees and VOC reach a maximum in summer time. Opposite seasonal variation are observed
for SO2.
Maximal level of SO2 is observed in winter and is stipulated by seasonal differences in the wind direction. Sinks of
trace gases depend on the meteorological conditions: height of mixing layer (which is maximal in summer), losses on the
surfaces (minimal in winter for snow cover), losses
in the canopies (maximal in summer time), the influence of RH on the condensation sink.
The seasonal variations formation particles is result from a balance of sources and sinks and demand a thorough
analysis in future.
