[en] Nadir observations of the Mars Aurora and dust Camera (M-AC) will characterize the morphology of the OI emission at 557.7 nm and its variability on short timescales. Limb images will provide key information on the vertical distribution of the energy deposition in the upper atmosphere. These observations will be compared with simultaneous in situ measurements of electron and ion precipitation by instruments such as M-EPI and M-COMPASS in different types of aurorae. The measured characteristics of the auroral particle flux will be used as input to energy deposition and excitation models for comparison with the M-AC observations at the footprint of the energetic particle precipitation. We will present examples of earlier studies based on Mars Express and MAVEN simultaneous in situ measurements and ultraviolet observations. Differences between these previous UV observations and the oxygen green line will be discussed, especially in the context of solar energetic events.
