Carbon photochemistry at Mars: Updates with recent data

Yelle, Roger V.; Lillis, Robert J.; Lo, Daniel Y.

We provide a comprehensive characterization of the photochemistry behind atomic carbon in the Mars atmosphere. Using a one-dimensional photochemical model, with an extensive reaction list incorporating new high-resolution photodissociation cross-sections (Heays et al., 2017) and the recently experimentally confirmed CO₂ + hν →C +O_2…
