Abstract
photochemical calculations for Uranus predict an extensive region of condensation
of acetylene, ethane and methane in the vicinity of the temperature inversion layer. This
could explain why ethane was not detected on Uranus, unlike Neptune which has a much warmer
inversion layer. Subsequent snow-out of the condensibles is expected to result in reduced
visibility in the troposphere. Ionospheric calculations for the equatorial region to be
probed by Voyager, indicate peak electron concentrations on the order of 5x1+ cme3, if
dynamical effects are important. Upper limit to the electron peak is 3~10~ cmw3. Exospheric
temperatures as high as 200-250K are conceivable.
