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-nucleation. A quasi-stationary
sectional approach is used to describe the size distribution change due
and a hybrid equilibrium/dynamical mass-transfer method
has been developed to lower the computational burden. SIREAM uses the same physical
parameterizations as those used in the Modal Aerosol Model, MAM
Sartelet et al. (2006). It is hosted in the modeling
system Polyphemus Mallet et al., 2007, but can be linked to
any other three-dimensional Chemistry-Transport Model.
