Abstract
We present a classification and a frequency of the new particle formation (NPF) bursts observed in the atmosphere over boreal zone of West Siberia, which are based on the data of continuous in situ measurements of the aerosol size distribution carried out in a wide range at two stations for atmospheric composition monitoring IAO SB RAS owned. Analysis of the data obtained from 2010 to 2013 showed that NPF bursts happen during 20-30% days analyzed. The most part of the NPF events are observed in spring (from March to May), and a secondary maximum is typical for September. Seasonal pattern and annual mean NPF frequency observed in West Siberia are similar to ones observed in boreal forests at background stations of Scandinavia, at that our data are in close agreement with long-term observations of SMEAR II station (Hyytiälä).
