      abstract     = {Secondary organic aerosol (SOA) formation has been
                      investigated as a function of temperature and humidity for
                      the ozone-initiated reaction of the two monoterpenes
                      alpha-pinene (243-313 K) and limonene (253-313 K) using the
                      84.5 m(3) aerosol chamber AIDA. This paper gives an overview
                      of the measurements done and presents parameters
                      specifically useful for aerosol yield calculations. The
                      ozonolysis reaction, selected oxidation products and
                      subsequent aerosol formation were followed using several
                      analytical techniques for both gas and condensed phase
                      characterisation. The effective densities of the SOA were
                      determined by comparing mass and volume size distributions
                      to (1.25 +/- 0.10) g cm(-3) for alpha-pinene and (1.3 +/-
                      0.2) g cm(-3) for limonene. The detailed aerosol dynamics
                      code COSIMA-SOA proved to be essential for a comprehensive
                      evaluation of the experimental results and for providing
                      parameterisations directly applicable within atmospheric
                      models. The COSIMA-assisted analysis succeeded to reproduce
                      the observed time evolutions of SOA total mass, number and
                      size distributions by adjusting the following properties of
                      two oxidation product proxies: individual yield parameters
                      (alpha(i)), partitioning coefficients (K-i), vapour
                      pressures (p(i)) and effective accommodation coefficients
                      (gamma(i)). For these properties temperature dependences
                      were derived and parameterised. Vapour pressures and
                      partitioning coefficients followed classical
                      Clausius-Clapeyron temperature dependences. From this
                      relationship enthalpies of vaporisation were derived for the
                      two more and less volatile product proxies of alpha-pinene:
                      (59 +/- 8) kJ mol(-1) and (24 +/- 9) kJ mol(-1), and
                      limonene: (55 +/- 14) kJ mol(-1) and (25 +/- 12) kJ mol(-1).
                      The more volatile proxy components had a notably low
                      enthalpy of vaporisation while the less volatile proxy
                      components gave enthalpies of vaporisation comparable with
                      those of typical products from alpha-pinene oxidation, e. g.
                      pinonaldehyde and pinonic acid.},
