Abstract

An atmosphere - chemistry model hierarchy S. E. Bauer, B. Langmann & D. Jacob Max-Planck-Institute for Meteorology Bundesstrafle 55, D-20146 Hamburg, Germany EMa.il: susanne.bauer@dkrz.de Abstract To investigate the formation of photo smog in polluted air masses with numerical models a number of atmospheric and chemical processes on various scales have to be taken into account. Here a mesoscale Eulerian model hierarchy consisting of three one-way nested models is presented. The regional model REMO is nested in itself with a higher spatial resolution. Then then the non-hydrostatic model GESIMA is embedded in this simulation to resolve the meso-"/-scale. The atmo- sphere model GESIMA includes chemistry modules 'on-line', thus meteorological informations are available every model time step to calculate transport, transfor- mation and deposition of the chemical species. First results are presented for the summer smog measurement campaign FLU- MOB, carried out in eastern Germany in 1994.
