P34B:
Processes in the Present-Day Atmosphere of Mars III

Submit an Abstract to this Session



Session ID#: 32221

Session Description:
Recent observations from Mars orbiters, landers, and rovers provide a wealth of information on the Martian atmosphere. Surface weather is monitored by the Curiosity rover, while several orbiters perform atmospheric observations, covering atmospheric regions from the near-surface to the upper atmosphere. While observations have led to considerable progress in understanding the structure of the Martian atmosphere, the challenges of today are the identification and quantification of the underlying dynamical, chemical, and radiative processes that govern the Martian atmosphere. Modeling the past climate of Mars hinges upon a robust understanding of its present state. This session solicits observational and theoretical contributions that provide deeper insight into these processes in the present-day atmosphere of Mars. This includes studies on the connections between the upper and the lower atmosphere and on processes leading to upper atmospheric particle energization and escape to deep space.
