| Zusammenfassung |
| Simultaneous limb observations of HCOOH, CO, PAN, C2H6, O3, NOx and other species by
MIPAS in the upper troposphere and lower stratosphere are compared with results of the
chemical circulation model EMAC. To allow for point by point comparisons with the
satellite data, the tropospheric meteorology of the CCM is nudged by observations
of ECMWF. The method is used for evaluation and further development of the
new isoprene oxidation scheme MIM3 and also for checking and distinguishing
biogenic and anthropogenic emissions used in the model. We show that the model is
able to reproduce the main features of the observations, including the seasonal
cycle, and that proper modelling of isoprene chemistry (and to less extent terpene
chemistry) is critical for understanding the observed chemical composition of the upper
troposphere. |
