| Zusammenfassung |
| The chemical composition of terrestrial planetary atmospheres can be critically influenced by
the presence of trace species, which in turn, can act in catalytic cycles, affecting the
concentrations of major atmospheric gases, by providing alternative chemical reaction routes
(i.e., chemical pathways). Since the number of chemical species and reactions in such
complex systems can be very large (and hence, also the number of chemical pathways), it is,
generally, a challenging task to identify the important chemical pathways that determine the
abundance of major species. Therefore, effective methods for the investigation of such
reaction networks are required. In order to analyze the CO2-dominated atmosphere of
Mars, we use a new analysis tool (i.e., Pathway Analysis Program - PAP), which
is capable of identifying and also quantifying all chemical reaction pathways in
a reaction network. For this study, we apply PAP to the Caltech-JPL 1-D Mars
photochemical model to identify and analyze the dominant chemical processes involved in
CO2-production in Mars’ atmosphere. Results of our analysis with respect to the dominant
catalytic chemical cycles, governing Martian atmospheric CO2 will be discussed. |
