Abstract
A GIS-based model was developed so to predict Biogenic Volatile
Organic Compounds (BVOCs) emissions from the Italian forest ecosystems in
order to estimate the fraction of the Net Primary Production lost as reduced
carbon and to assess the impact of BVOCs in the formation of ozone and sec-
ondary organic aerosols. The performance of the model was verified by com-
paring the predictions with BVOC fluxes measured in a CarboItaly site using
the gradient method with tethered balloon profiles, but also with BVOC fluxes
measured in previous years. The agreement between observations and predic-
tions indicated a rather accurate estimation of the model and confirmed the
importance in the Italian peninsula of monoterpene emissions, expecially of the
fast reacting sabinene in areas dominated by
Fagus sylvatica
L. and
Castanea
sativa
L.
