A Finnish national project LIPIKA - Fine particles from traffic and
their relation to laboratory test measurements (1.9.2002-31.5.2005)
funded by the National Technology Agency (TEKES)
and the Ministry of Transport and Communications Finland
was established to study urban air quality and to find out
dilution methods and parameters to be used in laboratory measurements
to be comparable with real traffic measurements provided
by a mobile laboratory.
Unlike stationary measuring sites, the mobile laboratory enables
measurements under real city traffic conditions, chasing in tunnels
and other underground sites as well as surveys on roads and highways.
It is also useful for static measurements when the instruments should
be rapidly moved from site to site as for example, in dispersion studies.
The partners are Tampere University of Technology (coordinator), Finnish Meteorological
Institute, University of Helsinki and Finnish Institute of Occupational Health,
Helsinki Polytechnic, Technical Research Centre of Finland, and
Helsinki Metropolitan Area Council.
Fine particles are sampled during several weeks in 2003-2004
in different conditions such as winter, summer, weekend and
rush hour conditions.
