Short summary
We improve a method for modeling the interaction between solar wind and Mars that uses a hybrid model to fit the observed bow shock location to determine a corresponding exobase ion upflux. We applied the method to one Mars Atmosphere and Volatile Evolution orbit to study the effects on ion escape estimates of heavy-ion composition in the ionosphere, alpha particles in the solar wind, solar-wind velocity aberration, and electron temperature. We also studied the morphology of the escaping ions.
