Abstract. We briefly present in this short paper a new SIze REsolved Aerosol Model (SIREAM) which simulates the evolution of atmospheric aerosol by solving the General Dynamic Equation (GDE). SIREAM segregates the aerosol size distribution into sections and solves the GDE by splitting coagulation and condensation/evaporation. A moving sectional approach is used to describe the size distribution change due to condensation/evaporation and a hybrid method has been developed to lower the computational burden. SIREAM uses the same physical parameterizations as those used in the Modal Aerosol Model, MAM sartelet05development. It is hosted in the modeling system POLYPHEMUS (Mallet et al., 2006) but can be linked to any other three-dimensional Chemistry-Transport Model.

The Horvath–Kawazoe equation has been used for the determination of the pore size distribution (PSD) of four fractions of active carbon separated by elutriation on the basis of their different degrees of activation. A comparison of the pore size distribution functions for argon and benzene as adsorbates has been undertaken. For both adsorbates, correction factors including the adsorption in mesopores have been evaluated. The influence of these corrections on the PSD functions has been discussed. Quantitative evaluations of the PSD functions for these two different adsorbates and a comparison with the results of small-angle X-ray scattering measurements leads to the conclusion that it is possible to use the benzene isotherm as well as those of other adsorbates.
