Observations of giant planet atmospheres at wavelengths from the sub-millimeter to tens-of-centimeters provides information on composition and temperature over a wide altitude range. This can be used to study weather, cloud formation, dynamics, and the composition of these objects. This Research Opportunity is designed to carry out, interpret, and/or augment observations made at telescope arrays such as the Very Large Array (VLA) or Submillimeter Array (SMA). Projects may involve these or other telescopes, other wavelengths, or purely theoretical studies that explain or predict relevant observations. Applicants are encouraged to propose their own research ideas, but some areas of active interest are seasonal variability in the atmosphere of Uranus, retrieval techniques for use with image data, and the vertical structure and circulation of giant-planet tropospheres. The work is expected to improve our understanding of all giant planets, and can impact current and future space missions.
