Description
The upper atmosphere of mars cools by radiative emission from vibrationally-excited carbon dioxide. There are several vibrational states that contribute to the emission profile, and the low-lying excited states can be populated by a wide variety of v-v and v-t energy exchange processes in addition to solar pumping. Efficient collisional energy transfer mechanisms involving carbon dioxide can have a significant influence on the energy balance of the martian atmosphere; IT is critical that all of these processes are well-characterized. The proposed work focuses on laboratory measurement of the rate coefficients for collisional quenching of carbon dioxide in the eight lowest-lying vibrational states by the collision partners carbon dioxide and ground state atomic oxygen. The goals of this work are to reduce uncertainty in those rate parameters that already exist in the literature and to measure other parameters for the first time. The results of this work should help modelers reconcile observed martian atmospheric emissions with model predictions with greater precision and aid in the development of accurate non-LTE models for the upper atmosphere of mars.
