      abstract     = {The presence of organic coatings on aerosols may have
                      important consequences to the atmospheric chemistry, in
                      particular to the N2O5 heterogeneous hydrolysis. This is
                      demonstrated by recent experiments which show that the
                      uptake of N2O5 by aqueous aerosols is slowed considerably
                      when an organic coating consisting of monoterpene oxidation
                      products is added on the particles. To treat the mechanisms
                      behind the suppression, an extension of the resistor model,
                      which has been widely applied in investigation of the
                      heterogeneous uptake by aerosols, was derived. The extension
                      accounts for dissolution, diffusion, and chemical reactions
                      in a multilayered organic coating, and it provides a
                      parametrization for the heterogeneous uptake by
                      organic-coated aerosols that can be applied in large-scale
                      models. Moreover, the framework was applied to interpret the
                      findings regarding the decreased uptake of N2O5 by the
                      organic-coated aerosols. Performed calculations suggested
                      that the reaction rate constant of N2O5 in the coating is
                      decreased by 3-5 orders of magnitude, in addition to which
                      the product of the solubility of N2O5 and its diffusion
                      coefficient in the coating is reduced more than an order of
                      magnitude compared to the corresponding value for the
                      aqueous phase. The results suggest also that the
                      accommodation coefficient of N2O5 to such coatings is no
                      more than a factor of 2 smaller than that to pure water
                      surfaces. Finally, the relevance of the results to the
                      atmospheric N2O5 heterogeneous hydrolysis is discussed and
                      implications to planning further laboratory studies focusing
                      on secondary organic aerosol formation are pointed out.},
