Abstract

Measurements of the yield of important trace gas species such as ozone, evolved during photolytic reactions have been made under Martian environmental conditions in one of the The Open University’s Mars simulation chambers. The simulation chamber can mimic Martian temperatures and pressures and a UV solar simulator can be added to irradiate a Mars-like gas mixture within the chamber to drive chemical reactions. The concentration of trace gases is measured in situ using a Fourier Transform Infrared spectrometer (FTIR). The data obtained will be invaluable in improving the qualitative and quantitative representation of chemical species calculated using Mars global circulation models (MGCMs) and in interpreting a new suite of observational data such as from ExoMars Trace Gas Orbiter (TGO).
