Main topics:

NERI is an agency under the Ministry of Environment and Energy and its main responsibility is surveillance and research in the field of environmental problems in Denmark. The team which will be involved in the work of the network belongs to the Department of Atmospheric Environment (ATMI). ATMI is dealing with measurements, data analyses and development of models for practical applications. ATMI is in charge of both the background air monitoring programme and the National Air Quality Monitoring Programme (LMP III) for urban areas. The programme is carried out as a joint effort between the National Environmental Protection Agency (EPA), NERI and counties and municipalities in selected urban areas. NERI designed the programme and is responsible for analysis of the collected data and for reporting the results.

ATMI was co-ordinator for the recently completed research project on Air Pollution from Traffic in Urban Areas (SMP-Traffic) which was conducted within the framework of the Danish Environmental Research Programme in co-operation with several other Danish research institutions. The aim of the project was to obtain a more complete knowledge of processes governing air pollution from traffic in urban areas. The project comprised measurements of several pollution compounds in streets, traffic counts, extensive meteorological measurements and model development and evaluation. ATMI has a long tradition in development of applied air pollution models. Of special interest here is the Operational Street Pollution Model (OSPM). The model is designed for detailed (on hourly basis) calculations of dispersion and transformation (NO/NO2) of traffic pollution in urban streets. The model has been extensively tested on data from several sites in Denmark as well as in other European countries. The model has been applied in several projects dealing with evaluation of pollution from traffic in Danish cities. OSPM is also implemented in the British model ADMS-Urban, developed by the CERC team.

Large effort was placed upon ensuring the model validity for a broad range of meteorological and chemical conditions. However, new data will be very valuable for improving the performance of OSPM. In particular, CFD-modelling and wind-tunnel simulations will be assimilated into the next version of the model. The extensive data collected from the field measurements conducted by ATMI will be used for evaluation of other models in the network.

The traffic is one of the main sources of the particular matter (PM) pollution. The monitoring programme is now being extended to include optical size fractionating measurements of PM. In combination with other pollution measurements and meteorological observations this will allow study of the processes governing emissions, dispersion and transformations of particles as well as determination of source contributions.
