The model simulation of air pollution is further used to assess processes involved in climate change and to perform impact assessments for human health and vegetation. SMHI is tasked to support the Swedish government on the work with Short Lived Climate Pollutants, SLCP.
The air quality research group develops coupled model systems that cover the hemispheric, regional, urban and local scales. SMHI’s chemical transport model MATCH includes photochemistry and relevant processes for aerosol formation. Local models are developed to assess the air quality environment close to the major pollution sources, the road traffic and the residential wood combustion.
The overreaching goal is to contribute with information that leads to improved air quality and reduced impact in Sweden and globally. The interaction between air pollutants and climate change is addressed both in process studies and in impact assessments where MATCH is coupled to the Rossby Centre climate models.
