The distribution of NMHC in Europe: Results from the EUROTRAC TOR project
Abstract Within the EUROTRAC sub project TOR, an European network of advanced monitoring stations situated at representative sites is operated, starting in 1988. Within the EMEP Co-operative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe measurements of VOC started in August 1992. In this study the combined TOR-EMEP data base has been used. Sector analyses have been performed in order to distinguish between unpolluted and the polluted air masses at each site. The seasonal averages have been calculated for each sector and site, and the results are discussed. Data allocated to the unpolluted sectors represents the common European background, and in the winter similar NMHC concentrations are found at all sites north of 50°N. These sites cover the area from North Europe into the Arctic (79°N), and the small north-south gradient indicates that NMHC builds up in the northern troposphere in winter, probably due to an efficient meridional mixing and slow photochemical reactions..
