High spatial resolution infrared imaging of Jupiter: implications for the vertical cloud structure from five-micron measurements by Richard J Terrile( )

1 edition published in 1978 in Undetermined and held by 1 WorldCat member library worldwide

This study describes the design and construction of a 5 µm imaging system used at the Hale 5 m (200 inch) telescope to acquire high spatial resolution infrared images of Jupiter. These images, recorded in a spectral region clear of terrestrial and Jovian gaseous absorption, offer a unique look into the deep atmosphere and provide direct observational evidence for the existence of multiple layers of clouds in the Jovian atmosphere. Evidence of layering is provided by the observed trimodal nature and persistence of the 5 µm flux-frequency distribution of equal areas on the Jovian disk. This indicates that three distinct brightness temperatures have a higher probability of being observed than a continuum of temperatures, and that, despite significant observed variations in the lateral 5 µm cloud distribution, this phenomenon is a long term stable vertical cloud feature. Furthermore, the visible color differences correlate with areas of different 5 µm intensity, implying that the colors are due to reflection from areas of different chemistry or state at different levels in the atmosphere. Also, short time scales are observed for large 5 µm flux variations over extensive areas of the Jovian disk, supporting the concept that the redistribution of obscuring clouds accounts for the contrasts at 5 µm. Finally, the 5 µm limb-darkening and opacity models, derived from imaging and spectroscopic measurements, are consistent with multiple layering of clouds in the Jovian atmosphere. Further information about the Jovian clouds results from the combination of 5 µm spectroscopic and imaging data sets. From the shape of the 5 µm spectrum true maximum brightness temperatures are derived, corrected for the clearest regions in the Jovian atmosphere. Furthermore, from data on spectral line saturation, limits are placed on the 5 µm cloud reflectivity over the field of view of the spectrometer. With this information, combined with the knowledge of the spatial flux distribution from imaging
