Depletion of 13C in CO in the Atmosphere of Mars Suggested by ExoMars-TGO/NOMAD Observations

Depletion of 13C in CO in the Atmosphere of Mars Suggested by ExoMars-TGO/NOMAD Observations

The atmosphere of Mars is mainly composed by carbon dioxide (CO _2 ). It has been predicted that photodissociation of CO _2 depletes ^13 C in carbon monoxide (CO). We present the carbon ^13 C/ ^12 C isotopic ratio in CO at 30–50 km altitude from the analysis of the solar occultation measurements tak...
