abstract = {Emission of biogenic volatile organic compounds (VOC) which
on oxidation form secondary organic aerosols (SOA) can
couple the vegetation with the atmosphere and climate.
Particle formation from tree emissions was investigated in a
new setup: a plant chamber coupled to a reaction chamber for
oxidizing the plant emissions and for forming SOA. Emissions
from the boreal tree species birch, pine, and spruce were
studied. In addition, alpha-pinene was used as reference
compound. Under the employed experimental conditions, OH
radicals were essential for inducing new particle formation,
although O-3 (< 80 ppb) was always present and a fraction of
the monoterpenes and the sesquiterpenes reacted with ozone
before OH was generated. Formation rates of 3 nm particles
were linearly related to the VOC carbon mixing ratios, as
were the maximum observed volume and the condensational
growth rates. For all trees, the threshold of new particle
formation was lower than for alpha-pinene. It was lowest for
birch which emitted the largest fraction of oxygenated VOC
(OVOC), suggesting that OVOC may play a role in the
nucleation process. Incremental mass yields were $5\%$ for
pine, spruce and alpha-pinene, and $10\%$ for birch.
alpha-Pinene was a good model compound to describe the yield
and the growth of SOA particles from coniferous emissions.
The mass fractional yields agreed well with observations for
boreal forests. Despite the somewhat enhanced VOC and OH
concentrations our results may be up-scaled to eco-system
level. Using the mass fractional yields observed for the
tree emissions and weighting them with the abundance of the
respective trees in boreal forests SOA mass concentration
calculations agree within $6\%$ with field observations. For
a future VOC increase of $50\%$ we predict a particle mass
increase due to SOA of $19\%$ assuming today's mass
contribution of pre-existing aerosol and oxidant levels.},
