The Cassini spacecraft has just completed the first full year of its planned four-year orbital tour of the Saturnian system. The orbital tour has already included several Titan flybys allowing for observations of Titan's atmosphere from pole to pole. Spectra taken by the Composite Infrared Spectrometer (CIRS) in both nadir and limb viewing mode have been used to determine the thermal structure and trace gas abundances in Titan's middle atmosphere (stratosphere and mesosphere). We will present preliminary results of 1-D photochemical modeling of the hydrocarbons in Titan's middle atmosphere and compare the results to the CIRS derived equatorial and mid-latitude abundances.
