| Zusammenfassung |
| We present a new European plant-specific emission inventory for isoprene,
monoterpenes, sesquiterpenes and oxygenated VOC (OVOC), on a spatial
resolution of 0.089×0.089 degrees, for implementation in atmospheric
transport models.
The inventory incorporates more accurate data on foliar
biomass densities from several litterfall databases that became available in
the last years for the main tree species in Europe. A bioclimatic correction
factor was introduced to correct the foliar biomass densities of trees and
crops for the different plant growth conditions that can be found in Pan-Europe.
Long-term seasonal variability of agriculture and forest emissions
was taken into account by implementing a new growing season concept.
The 2004–2005 averaged annual total biogenic volatile organic compound (BVOC)
emissions for the Pan-European domain are estimated to be about 12 Tg with a
large contribution from the OVOC class of about 4.5 Tg and from monoterpenes of
about 4 Tg. Annual isoprene emissions are found to be about 3.5 Tg,
insensitive to the chosen emission algorithm. Emissions of OVOC were found to
originate to a large extent from agriculture. Further experiments on crop emissions
should be carried out to check the validity of the applied standard emission factors.
The new inventory aims at a fully transparent and verifiable aggregation of detailed
land use information and at the inclusion of plant-specific emission data.
Though plant-specific land use data is available with relatively high accuracy,
a lack of experimental biomass densities and emission data on terpenes,
sesquiterpenes and oxygenated VOC, in particular for agricultural plants, currently
limits the setup of a highly accurate plant-specific emission inventory. |
