As found by the Cassini GC-MS, a plethora of organics are produced in Titan's upper atmosphere by short UV, cosmic rays and Saturn's magnetospheric particles. These energy sources convert the CH4, and N2 into mainly C2H2, C2H4, HCN and HC3N, which reach a lower altitude at the observed mixing ratios of 3x10-6, 10-7-10-8, 3x10-7 and 10-9-10-10, respectively. Reaching down to midaltitudes, these unsaturated compounds are activated by UV irradiation and form a plethora of hydrocarbons and nitriles, which produced the thick layer of aerosols in Titan's atmosphere.
