      abstract     = {We used a monoterpene volume mixing ratio dataset measured
                      from 12 June 2006 to 24 September 2007 and from 1 June 2008
                      to 3 March 2009 at the SMEAR II station to quantify the
                      magnitude of anthropogenic monoterpene emissions aside from
                      biogenic origins, to examine the anthropogenic sources, and
                      to look at other associated pollutants. We discuss the
                      relations between increased monoterpene mixing ratios and
                      particle concentrations. We also characterize chemical
                      properties of aerosol particles during two monoterpene
                      pollution episodes in case studies. Out of 580 days
                      analyzed, anthropogenic monoterpene pollution episodes were
                      found on 341 $(58.8\%)$ days. The average monoterpene mixing
                      ratio increased from 0.19 to 0.26 ppbv due to the presence
                      of anthropogenic monoterpenes, which is equal to an increase
                      of $36.8\%.$ The observed anthropogenic monoterpenes were
                      mostly from the Korkeakoski sawmill. Other gas pollutants
                      might occasionally be emitted during the episodes, but did
                      not show clear association with anthropogenic monoterpenes.
                      Aerosol particle concentrations substantially increased
                      during episodes, and monoterpene mixing ratios showed strong
                      connections with Aitken mode particles both in number and
                      volume concentrations. Particles associated with monoterpene
                      episodes reached a CCN (cloud concentration nucleus) size.
                      The chemical characterizations of aerosol particles in case
                      studies show that the increase in aerosol particle mass was
                      mainly from secondary organic aerosol.},
