[hal-00665044] Effects of uncertain photolysis parameters on predictions of Titan's photochemistry models

The precision of the rates of the photolytic processes initiating the complex chemistry of Titan's upper atmosphere conditions strongly the predictivity of photochemical models. However, there was no thorough investigation of the impact of the different parameters describing these processes. For the first time, we deal here directly with uncertainty in the photolysis crosssections and branching ratios to estimate the photolysis rate constants and reassess their impact on model predictions.
