      abstract     = {[1] The Cryogenic Infrared Spectrometers and Telescopes for
                      the Atmosphere (CRISTA) instrument measured a variety of
                      trace gases globally with high spatial resolution during two
                      Space Shuttle missions. This paper concentrates on members
                      of the NOy family and highlights differences between CRISTA
                      1 (November 1994) and CRISTA 2 (August 1997). A sequential
                      assimilation technique is used to combine the CRISTA
                      measurements of total NOy fields with corresponding model
                      forecasts based on the National Center for Atmospheric
                      Research Research for Ozone in the Stratosphere and its
                      Evolution (ROSE) model. For this study we use a model
                      version driven by wind and temperature data provided by the
                      UK Met Office. NO2 and N2O show large- and medium-scale
                      structures caused by dynamical processes. N2O5 shows a
                      strong dependence on the aerosol load and solar zenith
                      angles. N2O5 and NO2 changes from CRISTA 1 to CRISTA 2 are
                      consistent with a reduction of aerosol concentrations in the
                      Southern Hemisphere and minor aerosol changes in the
                      Northern Hemisphere. For both missions the model reproduces
                      well the measured diurnal cycles of the NOy family members.
                      Measured diurnal variations of N2O5 and NO2 are consistent
                      with the nighttime production of N2O5 from NO2. Compared to
                      the effect of heterogeneous chemistry, the influence of
                      ozone and temperature changes on the NOy partitioning is
                      rather small. A model run based on a three-dimensional
                      aerosol field derived from CRISTA observations indicates
                      that zonal asymmetries in the background aerosol have strong
                      local effects on the N2O5 and NO2 distribution.},
