Development and validation of a model for PM10 in urban environments

The purpose of the project is to develop a validated model for calculation of PM10 concentrations in urban environments

We are using NO_x as a tracer and measurements of PM10 for estimation of emissions factors for PM10. This method has then been used for calculations of PM10 concentrations in the city of Stockholm with reasonable good result.

By combining air dispersion calculations, using a simple box model, with measured concentrations of NO_x or NO₂, daily NO₂ emissions in three cities in Sweden were calculated and compared with calculated emissions from a traffic emission model.

Duration: 2003-2004

Funded by: Swedish National Road Administration (SNRA) In co-operation with City of Stockholm Environment and Health Administration and Lunds University
