| Zusammenfassung |
| A high quality dataset on the photo-oxidation of benzene, toluene,
p-xylene and 1,3,5-trimethylbenzene has been obtained from experiments in the
European Photoreactor (EUPHORE), a large outdoor environmental reaction
chamber. The experiments were designed to test sensitive features of
detailed aromatic mechanisms, and the dataset has been used to evaluate the
performance of the Master Chemical Mechanism Version 3 (MCMv3). An updated
version (MCMv3.1) was constructed based on recent experimental data, and
details of its development are described in a companion paper. The MCMv3.1
aromatic mechanisms have also been evaluated using the EUPHORE dataset.
Significant deficiencies have been identified in the mechanisms, in
particular: 1) an over-estimation of the ozone concentration, 2) an
under-estimation of the NO oxidation rate, 3) an under-estimation of OH. The
use of MCMv3.1 improves the model-measurement agreement in some areas but
significant discrepancies remain. |
