Determining the escape rate of C over time is necessary to reconstructing the time-dependent history of volatiles on Mars. We report initial results from a one-dimensional spherical Monte Carlo calculation of photochemical escape fluxes and rates of atomic carbon from the Martian atmosphere. This model has recently been used to estimate the photochemical escape flux of O from Mars. We include as sources photodissociation of CO, dissociative recombination of CO+, photoelectron-impact dissociation of CO, photodissociative ionization and photoelectron impact dissociative ionization. Dissociative recombination of CO2+ has been suggested as a source of C (in the channel that produces C + O2) but later studies have found that the yield of this channel is negligible. We test the potential importance of this reaction by comparing the final results produced by including it and excluding it. Finally we compare the range of the escape rate to that of C in ions that have been modeled or measured by ASPERA instruments on MEX and Phobos.
