چکیده انگلیسی
Ethane and other C2 and C3 nonmethane hydrocarbons were observed by the Galileo Probe Mass Spectrometer to have a deep minimum in mixing ratio near and below the tropopause, rising to much larger values at and below the 15 bar level. This minimum requires that these hydrocarbons condense on smog particles at low temperatures. The large amounts at deeper levels were produced in the pumping system of the instrument and any contribution from the ambient atmosphere cannot be resolved, although evaporation from the smog particles is proposed and incorporated in a model. In the stratosphere some of the ethane is released by photon-stimulated desorption. The other light nonmethane hydrocarbons are not modeled, but can be expected to show the same behavior as ethane.
