  abstract = {{We present a study on diurnally and annually averaged values of the
actinic fluxes used in one-dimensional (1-D) photochemical models, as
well as a 3-D radiative transfer model, based on Monte Carlo
calculations with application to the atmosphere of Titan. This study
shows that the commonly used value {\lt}{\thetas}{\gt}=30{\deg} for the mean
incident angle at the equator in photochemical models of Titan is not
the best choice, though changing the value has no dramatic effects on
photochemistry. The results of the 3-D code give direct access to the
photolysis rates at any point in the atmosphere. The necessity of 3-D
values in a deep atmosphere such as Titan's is demonstrated particularly
for high-latitude winter conditions. These 3-D photolysis rates are used
to model the latitudinal variations of the chemical composition of
Titan's atmosphere in a 1-D photochemical model adapted to different
latitudes. This study shows that these kinds of simple photochemical
models cannot reproduce the observed latitudinal behavior and that we
need to develop real 2-D photochemical models of Titan's atmosphere.
