title: Regional and seasonal limitations for Mars intrinsic ecopoiesis.
abstract: Mars ecopoiesis is a human controlled process consisting in changes needed for anaerobic life to be established on planet surface. The daily minimum temperature on present day Mars is well below the water freezing point, due to the low thermal inertia of the surface. A simple time-dependent model to evaluate the ground temperature is developed here. It takes into account the incident solar radiation, the greenhouse effect and surface thermal inertia. The model is applied to two modified Martian atmospheres. Increasing surface thermal inertia seems to be necessary for Mars intrinsic ecopoiesis. This can be done either by removing the regolith layer covering the bedrock or by regolith compression. The Northern hemisphere of the terraformed Mars appears to be more hospitable than the Southern hemisphere, because the amplitude of the daily temperature excursion there is lower and the freezing temperature appears at higher latitudes. A regional (and seasonal) terraforming of Mars is suggested.
