      abstract     = {During the BERLIOZ field phase on 20 July 1998 a 40 km wide
                      ozone-plume 30 to 70 km north of Berlin in the lee of the
                      city was detected. The ozone mixing ratio inside the plume
                      was app. 15 ppb higher than outside, mainly caused by high
                      ozone precursor emissions in Berlin, resulting in a net
                      chemical ozone production of 6.5 ppb h(-1), which
                      overcompensates ozone advection of -3.6 ppb h(-1) and
                      turbulent diffusion of -1.1 ppb h(-1). That means, although
                      more ozone leaves the control volume far in the lee of
                      Berlin than enters it at the leeside cityborder and although
                      turbulent diffusion causes a loss of ozone in the leeside
                      control volume the chemical production inside the volume
                      leads to a net ozone increase. Using a semi-Lagrangian mass
                      budget method to estimate the net ozone production, 5.0 ppb
                      h(-1) are calculated for the plume. This means a fraction of
                      about $20\%$ of ozone in the plume is produced by local
                      emissions, therefore called 'home made' by the Berlin
                      emissions. For the same area KAMM/DRAIS simulations using an
                      observation based initialisation, results in a net
                      production rate between 4.0 and 6.5 ppb h(-1), while the
                      threefold nested EURAD model gives 6.0 ppb h(-1). The
                      process analysis indicates in many cases good agreement
                      $(10\%$ or better) between measurements and simulations not
                      only in the ozone concentrations but also with respect to
                      the physical and chemical processes governing the total
                      change. Remaining differences are caused by different
                      resolution in time and space of the models and measurements
                      as well as by errors in the emission calculation.The
                      upwind-downwind differences in PAN concentrations are partly
                      similar to those of ozone, because in the BERLIOZ case they
                      are governed mainly by photochemical production. While in
                      the stable boundary layer at night and windward of Berlin
                      0.1 to 0.3 ppb are detected, in the centre of the plume at
                      noon concentrations between 0.75 ppb and 1.0 ppb are
                      measured. The O-3/PAN ratio is about 80 to 120 and thus due
                      to the relatively low PAN concentrations significantly
                      higher than found in previous studies. The low PAN formation
                      on 20 July, was mainly restricted by the moderate nonmethane
                      hydrocarbon levels, whereas high PAN concentrations of 3.0
                      ppb on 21 July, are caused by local production in the
                      boundary layer and by large scale advection aloft.},
