This Hirise perspective view of Candor Chasma is of a nearby area to that of the Mars Express image showing the dense low lying clouds/fogs:

judging from the latitude/longitude of the image given in the "Adsorption water driven processes on Mars" report.

The seasonal time when the Mars Express image was taken in mid southern Autumn is coming up on Mars. Mars is known to present seasonal cloud belts during this time. It is likely these dense clouds/fogs will be repeated in this region.
A perspective view may make it possible to find out how low these clouds/fogs go and if they contact the surface. If so, there may become visible seasonal meteorologically generated features.
