Existing parameterizations tend to underpredict the α-pinene aerosol
mass fraction (AMF) by a factor of 2–5 at low organic aerosol concentrations
(<5 μg m<sup>−3</sup>). A wide range of smog chamber results obtained at
various conditions (low/high NO<sub>x</sub>, presence/absence of UV radiation,
dry/humid conditions, and temperatures ranging from 15–40°C) collected
by various research teams during the last decade are used to derive new
parameterizations of the SOA formation from α-pinene ozonolysis.
Parameterizations are developed by fitting experimental data to a basis set
of saturation concentrations (from 10<sup>−2</sup> to 10<sup>4</sup> μg m<sup>−3</sup>)
using an absorptive equilibrium partitioning model. Separate
parameterizations for α-pinene SOA mass fractions are developed for:
1) Low NO<sub>x</sub>, dark, and dry conditions, 2) Low NO<sub>x</sub>, UV, and dry conditions, 3)
Low NO<sub>x</sub>, dark, and high RH conditions, 4) High NO<sub>x</sub>, dark, and dry
conditions, 5) High NO<sub>x</sub>, UV, and dry conditions. According to the proposed
parameterizations the α-pinene SOA mass fractions in an atmosphere
with 5 μg m<sup>−3</sup> of organic aerosol range from 0.032 to 0.1 for
reacted α-pinene concentrations in the 1 ppt to 5 ppb range.
