Sensitivity of ozone concentrations in the LOTOS-EUROS model

The study reported here describes the influence on ozone concentrations in the LOTOS-EUROS model of model parameters, chemistry scheme, VOC emissions, NO_x emissions, convergence of the chemistry scheme, washout ratios in wet deposition, emission time profiles and the boundary conditions for ozone. The most important outcome of this study was that results were found to be highly dependent on the applied chemistry scheme, boundary ozone concentrations and NO_x emissions and less dependent on the implemented VOC split and washout ratios.
