The infrared spectroscopy and radiometry investigation has obtained spectra of Jupiter and its satellites between approximately 180 and 2500 cm–1 with a spectral resolution of 4.3cm–1, showing clear evidence of H2, CH4 C2H2, C2 H6, CH3D, NH3, PH3, H2O, and GeH4.Abstract:
The infrared spectroscopy and radiometry investigation has obtained spectra of Jupiter and its satellites between approximately 180 and 2500 kayser with a spectral resolution of 4.3 kayser. The Jupiter spectra show clear evidence of H2, CH4, C2H2, C2H6, CH3D, NH3, PH3, H2O, and GeH4. A helium concentration of 0.11 plus or minus 0.03 by volume is obtained. Meridional temperature cross sections show considerable structure. At high latitudes, the stratosphere is warmer in the north than in the south. The upper troposphere and lower stratosphere are locally cold over the Great Red Spot. Amalthea is warmer than expected. Considerable thermal structure is observed on Io, including a relatively hot region in the vicinity of a volcanic feature.read more

TL;DR: The cameras aboard Voyager 1 have provided a closeup view of the Jupiter system, revealing heretofore unknown characteristics and phenomena associated with the planet's atmosphere and the surfaces of its five major satellites.

TL;DR: During the passage of Voyager 1 through the Saturn system, the infrared instrument acquired spectral and radiometric data on Saturn, the rings, and Titan and other satellites, implying a depletion of helium in the atmosphere of Saturn relative to that of Jupiter.

TL;DR: Voyager 2, during its encounter with the Jupiter system, provided images that both complement and supplement in important ways the Voyager 1 images, which revealed a complex and, as yet, little-understood system of overlapping bright and dark linear features.

TL;DR: The thermal structure of the Venus atmosphere and differences in structure with latitude (up to 60 deg) and clock hour (from midnight to 8 AM) have been measured in situ from a height of 126 km to the surface by instruments on the four Pioneer Venus entry probes as discussed by the authors.

TL;DR: The Composite Infrared Spectrometer (CIRS) is a remote-sensing Fourier transform spectrometer on the Cassini orbiter that measures thermal radiation over two decades in wavenumber, with a spectral resolution that can be set from 0.5 to 15.5 cm− 1.

Propagation of planetary‐scale disturbances from the lower into the upper atmosphere
J. G. Charney,P. G. Drazin +1 more
TL;DR: In this paper, the authors investigated the possibility that a significant part of the energy of the planetary-wave disturbances of the troposphere may propagate into the upper atmosphere and found that the effective index of refraction for the planetary waves depends primarily on the distribution of the mean zonal wind with height.

Melting of Io by Tidal Dissipation
TL;DR: The dissipation of tidal energy in Jupiter's satellite Io is likely to have melted a major fraction of the mass, and consequences of a largely molten interior may be evident in pictures of Io's surface returned by Voyager I.

Theory of line shape in pressure-induced absorption
George Birnbaum,E. Richard Cohen +1 more
TL;DR: In this paper, a quantum theory of line shape in pressure-induced absorption giving relatively simple results in closed form is developed, which is applied to far infrared spectra: the translational spectrum of He-Ar, the well resolved S(0) rotational line of H2 at 77 K, and the unresolved rotational band of N2.
