Abstract

Measurements of Vertical Fluxes of VOCs above Boreal Forests A contribution to subproject BIATEX-2 H.J.I. Rinne, T. Laurila and H Hakola Finnish Meteorological Institute, Air Quality Research, Sahaajankatu 20 E, FIN-00810 Helsinki, Finland Introduction The boreal vegetation zone is assessed as being one of the major sources of biogenic volatile organic compounds (BVOCs) in the atmosphere. In Europe, the boreal vegetation covers large areas in Sweden, Finland and northern Russia. The dominant tree species in the boreal forests in Finland are Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). These species are known to be monoterpene emitters (Isidorov et al., 1995; Janson, 1993; Steinbrechereftf/., 1993). Measurements As a part of the BIPHOREP project, the Finnish Meteorological Institute has conducted two micrometeorological campaigns during the summers 1996 and 199
