      abstract     = {Polar ozone loss in late winter and early spring is caused
                      by enhanced concentrations of active chlorine. The surface
                      necessary for heterogeneous reactions activating chlorine
                      species is provided by cold stratospheric aerosols and polar
                      stratospheric clouds (PSCs). Moreover, sedimentation of PSC
                      particles changes the chemical composition of the lower
                      stratosphere and alters the process of ozone depletion by
                      irreversible redistribution of nitric acid and water
                      vapor.The Chemical Lagrangian Model of the Stratosphere
                      (CLaMS) simulates the nucleation, growth, sedimentation, and
                      evaporation of PSC particles along individual trajectories.
                      Particles consisting of nitric acid trihydrate (NAT) were
                      the focus of previous work and are known for their potential
                      to denitrify the polar stratosphere. Here, we carried this
                      idea forward and introduced the formation of ice PSCs and
                      the related dehydration within the sedimentation module of
                      CLaMS.We show results from the Arctic winter 2009/2010,
                      which is already well characterized because of the RECONCILE
                      aircraft campaign and connected work. CLaMS simulations from
                      the Antarctic winter 2011 complete this study and
                      demonstrate the model's performance over an entire PSC
                      season in the Southern Hemisphere. For both hemispheres, we
                      present CLaMS results in comparison to PSC observations from
                      the Cloud-Aerosol Lidar with Orthogonal Polarization
                      (CALIOP) and the Michelson Interferometer for Passive
                      Atmospheric Sounding (MIPAS). Moreover, we confront CLaMS
                      simulations of water vapor with vortex-wide Microwave Limb
                      Sounder (MLS) observations. Observations and simulations are
                      compared on season-long and vortex-wide scales as well as
                      for single PSC events. The simulations reproduce well both
                      the timing and extent of PSC occurrence inside the entire
                      vortex. Divided into specific PSC classes, CLaMS results
                      show good agreement with CALIOP and MIPAS observations, even
                      for specific days and single satellite orbits. The vertical
                      redistribution of nitric acid and water during the polar
                      winter season, as seen in the MLS data, is visible in the
                      CLaMS data as well. Overall, a conclusive agreement between
                      CLaMS and a variety of independent measurements is
                      presented.},
