Abstract: Two new model tools have been developed for meeting the EU Air Quality Directive targets: SIMAIRroad (related to traffic emissions) and SIMAIRrwc (rwc standing for residential wood combustion). The models have been evaluated for different traffic situations and for residential areas with wood combustion, with promising results. The models can calculate PM10 statistics, such as mean values and 90 and 98 percentiles, that are well within ±50%. In fact, most of the results are within ±25%. Studded tyres are one important factor causing high PM10 concentrations in Swedish streets, so reducing their use would considerably improve air quality.
