	<abstract content_type="html">The new Modular Earth Submodel System (MESSy) describes atmospheric
  chemistry and meteorological processes in a modular framework, following
  strict coding standards. It has been coupled to the ECHAM5 general
  circulation model, which has been slightly modified for this purpose. A
  90-layer model setup up to 0.01 hPa was used at spectral T42
  resolution to simulate the lower and middle atmosphere.
  With the high vertical resolution the model simulates the
  Quasi-Biennial Oscillation.
  The model
  meteorology has been tested to check the influence of the changes to ECHAM5
  and the radiation interactions with the new representation of atmospheric
  composition.  In the simulations presented here a Newtonian relaxation
  technique was applied in the tropospheric part of the domain to weakly nudge
  the model towards the analysed meteorology during the period 1998&amp;ndash;2005.
  This allows an efficient and direct evaluation with satellite and in-situ
  data.
  It is shown that the tropospheric wave forcing of the stratosphere in
  the model suffices to reproduce major stratospheric warming events
  leading e.g.&amp;nbsp;to the vortex split over
  Antarctica in 2002.  Characteristic features such as dehydration and
  denitrification caused by the sedimentation of polar stratospheric cloud
  particles and ozone depletion during winter and spring are simulated well,
  although ozone loss in the lower polar stratosphere is slightly
  underestimated. The model realistically simulates stratosphere-troposphere
  exchange processes as indicated by comparisons with satellite and in situ
  measurements. The evaluation of tropospheric chemistry presented here
  focuses on the distributions of ozone, hydroxyl radicals, carbon monoxide
  and reactive nitrogen compounds. In spite of minor shortcomings, mostly
  related to the relatively coarse T42 resolution and the neglect of
  inter-annual changes in biomass burning emissions, the main characteristics
  of the trace gas distributions are generally reproduced well.  The MESSy
  submodels and the ECHAM5/MESSy1 model output are available through the
  internet on request.</abstract>
