摘要: Abstract An inventory describing the fluxes of volatile organic compounds (VOCs), isoprene and monoterpenes, other VOCs (OVOCs) from biosphere to atmosphere, has been constructed within framework ESCOMPTE project (fiEld experimentS COnstrain Models atmospheric Pollution Transport Emissions). The area concerned, located around Berre-Marseilles, is a Mediterranean region frequently subject high ozone concentrations. developed using fine scale land use database for year 1999, forest composition statistics, emission potentials individual plant species, biomass distribution, temperature light intensity. seasonal variations in were also taken into account. Hourly meteorological data 1999 calculated ALADIN these used predict hourly isoprene, monoterpene OVOC on 1 km × 1 km spatial grid. Estimates annual biogenic reference 20.6, 38.9 13.3 kt, respectively, Quercus pubescens , ilex Pinus halepensis garrigue vegetation are dominant emitting species area. VOC emissions this contribute approximately 94% NMVOC (non-methane compounds) natural origin same order magnitude as anthropogenic sources. These results complete global needed make an efficient strategy tropospheric reduction policy.
