High Altitude Hazes

By Candy on 2017-12-28 UT

Our first PJ1 images showed a high altitude cloud extending above the terminator.  Other images show bands of haze.

    Attached is a more detailed description of how to find the limb in an image, how to rectify it, and how to get an idea about the structure of the hazes along the limb.

    Here is our abstract for my talk given at the EPSC in Berlin in 2018 September, summarising the main patterns of haze bands in both hemispheres:

    The subcomments of this comment will be used for a more complete survey of Jupiter's limb. The rectification algorithm is refined, and uses the mean brightness of the zone of the steepest brightness slope as a definition for limb.

    Attached is a PJ12 survey. Considered are only close-up RGB images with the terminator outside the field of view.

    In PJ12, image #87, there is a section of a limb showing two layers of presumably detached haze. This might hint towards four stacked separate weather systems, three of which forming their own inversion layer. On Earth, inversion layers form when warm air is layered above cold air. For Jupiter, it's usually assumed, that temperature is decreasing with altitude. This assumption would suggest hazes of different chemical composition resublimating for specific temperature and pressure conditions, which gradually change with altitude.

    A more complete survey of the Jupiter's limb during PJ14.

    Here a crop of the brightness gradient, where a detached haze layer occurs.
