Jupiter's Deep Cloud Structure Revealed Using Keck Observations of Spectrally Resolved Line Shapes

  title={Jupiter's Deep Cloud Structure Revealed Using Keck Observations of Spectrally Resolved Line Shapes},
  author={G. Bjoraker and M. Wong and I. Pater and M. 'Ad'amkovics},
  journal={arXiv: Earth and Planetary Astrophysics},
Technique: We present a method to determine the pressure at which significant cloud opacity is present between 2 and 6 bars on Jupiter. We use: a) the strength of a Fraunhofer absorption line in a zone to determine the ratio of reflected sunlight to thermal emission, and b) pressure-broadened line profiles of deuterated methane (CH3D) at 4.66 microns to determine the location of clouds. We use radiative transfer models to constrain the altitude region of both the solar and thermal components of… Expand

How Well Do We Understand the Belt/Zone Circulation of Giant Planet Atmospheres?
This review is an attempt to reconcile the observed properties of belts and zones with (i) the meridional overturning inferred from the convergence of eddy angular momentum into the eastward zonal jets at the cloud level on Jupiter and Saturn and the prevalence of moist convective activity in belts; and (ii) the opposingMeridional motions inferredfrom the upper tropospheric temperature structure, which implies decay and dissipation of the zonal Jets with altitude above the clouds.
