hot air ArMaP ? .., what about the cooloer air.. no vortex without that :D
Hotter air implies hotter than something else, and that something else is, obviously, cooler air. :)

Quotebut this is all additional to the temperature inversions that may or may not be causing fog
you cannot deny though that early morning have a certain haze about them :D
The problem is in ignoring that the haze remains throughout the day, until sunset (we don't have night photos to show if the haze is still there).

Yes, there's haze in the morning, but the haze remains for the whole day, and the next, and the next, and is consistent with dust in the air.

Yes, we have photos of what appears to be fog, but not on Gale crater, unless I miss those.

do you have accumulated evidence to say that for certain ? ide like to see a full day sequence to know that for certain. you say theres no night photos *Dark chuckling* , but then there isn't  a set of photos that show a full day cycle. unless you have seen such a set?

I saw a full day sequence from (I think) the NavCams some months ago, but I don't remember if it showed a wide area or just an area close to the rover, I have to look for it.

For now, the closest I can get to that is this:
Taken at 11:53 AM (Mars local time)



Taken at 04:53 PM (Mars local time)



PS: a correction regarding night photos, we do have night photos, but they are either from the sky (showing stars or Mars natural satellites) or from MAHLI, usually showing a small area of the ground illuminated by the camera's LEDs.

did you white balance the pictures beforehand?

there's no point in relying on Rawjpg's there's no color truth in them until true white is identified

but asides the obvious colour nonsense , ill wait until ive seen the full set .. do you remember if they kept the same framed shot for all the sequences?

No, if you look at the source you can see they are on NASA's site.

You can always wait for the radiometrically corrected versions posted on the PDS.

From what I remember it was always the same scene.
