The heavily processed JunoCam image at left shows long bands of haze in Jupiter's northern hemisphere. It was obtained during the PJ25 flyby on February 17, 2020. The haze appears slightly bluish and casts brownish shadows on the cloud deck below.
The image at right was obtained by Landsat 8 on May 9, 2021 and might be of peripheral interest when looking at hazes in the JunoCam images. It is processed from bands 4, 3 and 2 (red/green/blue) and includes the site of the ongoing Geldingadalir volcanic eruption in Iceland. The volcanic plume containing sulphur dioxide (SO2) among other things is clearly visible; clouds and hazes associated with it extend to the west (or WSW). What this has in common with the image of Jupiter is that the plume and associated haze also appears slightly bluish and casts brownish shadows (this can be verified by looking at earlier images; the shadows are real features, there are no dark and/or brownish areas where the shadows are located). This image is slightly enhanced to better show the plume and the shadows and the color saturation was also increased. The JunoCam image is more heavily processed.
This comparison between JunoCam and Landsat images was inspired by a Facebook post from the Volcanology and Natural Hazard Group at the University of Iceland which posted a different version of this Landsat image (different bands were used) and mentioned the bluish haze and yellowish/brownish shadows from the plume.
