A total of 20 research teams from across Europe have set up sites in the Île-de-France (a region that includes the Paris metropolitan area) to quantify sources of particulate pollution in the urban environment.
The campaign is being carried out as part of the EU-funded MEGAPOLI project, which is being supported by €3.4m (£2.9m) in funding from the European Seventh Framework Programme (FP7).
MEGAPOLI is being co-ordinated by the Danish Meteorological Institute (DMI) and involves partners from 12 European countries including the Czech Republic, France, Greece, Italy, Switzerland and the UK.
Ground-based observations are being carried out at three sites, including the Paris Hygiene Laboratory.
The results of the study will enable the researchers to further assess and revamp existing models used for forecasting and simulating air pollution.
The researchers expect to launch another field campaign in late 2009, early 2010.
