On Earth, a microclimate mostly refers to an area which differs from the surrounding areas in temperature or humidity.
And what about Mars ?
Are there places with atmospheric conditions that are less unpleasant for humans than those in general on the rest of Mars, like higher temperature, less wind, less dust and without dust storms ?
Ganges Cavus for instance, is a collapse feature lying in the eastern part of the Valles Marineris system of canyons.
It is an elliptical depression with a width that varies from about 30 to 40 km and is more than 6 km deep. According to this article the floor of the cavus is <20 km long from east to west.
At the high plains surrounding Ganges Cavus the atmospheric pressure will be well below the average pressure of 600 pascals on the Martian surface, while the pressure at the floor will have about the double value.
Could it be that dust storms will flow more or less above Ganges Cavus because of this difference in pressure and the depth of this depression ?
And are there other places on Mars where better weather conditions could exist ?
According to figure 1 of this article for instance, there are some craters with a diameter of about 1 km with a depth of more than 200 meters ! When near the equator, could they not contain a microclimate ?
