Photochemical oxidants

A photochemical module was added to MATCH in the mid nineties. The module is based on the EMEP photochemical scheme but has undergone several changes over the years in order to be applicable in different projects. Photochemical modelling has been performed mainly over Europe. The MATCH photochemical model has been evaluated, and compared with other regional scale models, in several projects. The main problem areas are listed below.

• Ozone forecasting

• Assessments of emission reductions in Sweden and Europe

• Impacts of aviation emissions

• Trends in peak ozone concentrations
