This research combines the acquisition, reduction and analysis of remote-sensing data on planetary atmospheres with theoretical models of structure and dynamics. Much of the data involves infrared imaging and spectroscopy, and data have been acquired from experiments on spacecraft such as Galileo, Cassini, Hubble and Spitzer. Observations are also acquired from a vigorous ground-based astronomy program emphasizing the near and middle infrared, but including other spectral regions. They have involved traditional, remote or service observing at NASA's Infrared Telescope Facility, Palomar, Keck, Gemini, Subaru and the Very Large Telescope. These observations have focused on deriving thermal structure, bulk and trace constituent abundances, and cloud properties. This work on data acquisition and analysis is combined with more recent efforts to simulate atmospheric dynamics and model energy transfer mechanisms in these atmospheres, as constrained by our acquired data. Opportunities exist over this broad range of research.
