<abstract>
<p>We present the first detailed microphysical simulations which are performed
online within the framework of a global 3-D chemical transport model (CTM)
with full chemistry. The model describes the formation and evolution of four
types of polar stratospheric cloud (PSC) particles. Aerosol freezing and
other relevant microphysical processes are treated in a full explicit way.
Each particle type is described by a binned size distribution for the number
density and chemical composition. This set-up allows for an accurate
treatment of sedimentation and for detailed calculation of surface area
densities and optical properties. Simulations are presented for the Antarctic
winter of 2003 and comparisons are made to a diverse set of satellite
observations (optical and chemical measurements of POAM III and MIPAS) to
illustrate the capabilities of the model. This study shows that a combined
resolution approach where microphysical processes are simulated in
coarse-grained conditions gives good results for PSC formation and its
large-scale effect on the chemical environment through processes such as
denitrification, dehydration and ozone loss.</p>
