Conclusions. A comprehensive model is proposed to compute dayglow and nightglow emissions of the Venusian upper atmosphere. It relies on previous studies with noticeable improvements, both on the transport and on the chemical aspects. Observations and simulations are in good agreement and can prepare for comparisons with SPICAV onboard Venus Express. This study shows also that fundamental uncertainties remain concerning the origin of the green line nightside production. Deciding which process is at its origin will require new lab and satellite experiments.
