      abstract     = {Simulations of the development of the chemical composition
                      of the Arctic stratosphere for spring 2000 are made with the
                      Chemical Lagrangian Model of the Stratosphere (CLaMS). The
                      simulations are performed for the entire Northern Hemisphere
                      on four isentropic levels (400-475 K). The initialization in
                      early February is based on observations made from satellite,
                      balloon and ER-2 aircraft platforms. Tracer-tracer
                      correlations from balloon-borne cryosampler (Triple) and
                      ER-2 measurements, as well as tracer-PV correlations, are
                      used to derive a comprehensive hemispherical initialization
                      of all relevant chemical trace species. Since significant
                      denitrification has been observed on the ER-2 flights, a
                      parameterization of the denitrification is derived from NOy
                      and N2O observations on board the ER-2 aircraft and the
                      temperature history of the air masses under consideration.
                      Over the simulation period from 10 February to 20 March, a
                      chemical ozone depletion of up to $60\%$ was derived for
                      425-450 K potential temperature. Maximum vortex-averaged
                      chemical ozone loss rates of 50 ppb d(-1) or 4 ppb per
                      sunlight hour were simulated in early March 2000 at the 425
                      and 450 K potential temperature levels. We show comparisons
                      between the measurements and the simulations for the
                      location of the ER-2 flight paths in late February and March
                      and the location of the Triple balloon flight. The simulated
                      tracer mixing ratios are in good agreement with the
                      measurements. It was not possible to reproduce the exact
                      details of the inorganic chlorine compounds. The simulation
                      agrees with ClOx observations on the Triple balloon flight
                      but overestimates for the ER-2 flights. The simulated ozone
                      depletion agrees with estimates from other observations in
                      the 425 and 450 K levels, but is underestimated on the 475 K
                      level.},
