Description
Jupiter's atmosphere has been sounded in transmission from UV to IR, as
if it were a transiting exoplanet by observing one of its satellites,
Ganymede, while passing through Jupiter's shadow during a solar eclipse
from Ganymede. The spectra show strong extinction due to the presence of
aerosols and haze in the atmosphere and strong absorption features from
CH4.In addition, the spectra show two broad features near 1.5 and
2.0μm that we tentatively attribute to a layer of H2O ice in
Jupiter's stratosphere. While the spectral signatures seem to be
unequivocally attributed to crystalline water ice, to explain the strong
absorption features requires a large amount of water ice.
