      abstract     = {Recent satellite observations and dynamical studies have
                      demonstrated the existence of filamentary structures in
                      chemical tracer fields in the stratosphere. It is also
                      evident that such features are often below the spatial
                      resolution of the highest-resolution Eulerian models that
                      have been used up to the present time. These observations
                      have motivated the development of a novel Chemical
                      Lagranigan Model of the Stratosphere (CLaMS) that is based
                      on a Lagrangian transport of tracers. The description of
                      CLaMS is divided into two parts: Part 1 (this paper)
                      concentrates on the Lagrangian dynamics, i.e., on the
                      calculation of trajectories and on a completely new mixing
                      algorithm based on a dynamically adaptive grid, while part 2
                      describes the chemical integration and initialization
                      procedure. The mixing of different air masses in CLaMS is
                      driven by the large-scale horizontal flow deformation and
                      takes into account the mass exchange between the nearest
                      neighbors determined by Delaunay triangulation. Here we
                      formulate an isentropic, i.e., two-dimensional version of
                      the model and verify the mixing algorithm using tracer
                      distributions measured during the space shuttle CRISTA-1
                      experiment where highly resolved stratospheric structures
                      were observed in early November 1994. A comparison of the
                      measured Southern Hemispheric N2O distribution with CLaMS
                      results allows the intensity of simulated mixing to be
                      optimized. The long-term robustness of the transport scheme
                      is investigated in a case study of the 1996-1997 Northern
                      Hemisphere polar vortex. This study further provides a
                      dynamical framework for investigations of chemical arctic
                      ozone destruction discussed in part 2.},
