	<abstract content_type="html">We briefly present in this short paper a new SIze REsolved Aerosol Model
(S&lt;small&gt;IREAM&lt;/small&gt;) which simulates the evolution of atmospheric aerosol by
solving the General Dynamic Equation (GDE).  S&lt;small&gt;IREAM&lt;/small&gt; 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
to condensation/evaporation,
and a hybrid equilibrium/dynamical mass-transfer method
has been developed to lower the computational burden.  S&lt;small&gt;IREAM&lt;/small&gt; uses the same physical
parameterizations as those used in the Modal Aerosol Model, M&lt;small&gt;AM&lt;/small&gt;
Sartelet et al. (2006). It is hosted in the modeling
system P&lt;small&gt;olyphemus&lt;/small&gt; Mallet et al., 2007, but can be linked to
any other three-dimensional Chemistry-Transport Model.</abstract>
