Extreme model atmosphere of mars

Abstract : Theoretical models of the atmosphere of Mars were computed on the basis of present factual knowledge with a minimum of assumptions. The resultant model atmosphere gives extreme upper and lower limits for pressure, temperature, and density in the Martian atmosphere up to 150 km altitude. While this rigorous method yielded reliable data needed for the engineering design of space probes, the spread of values is still extremely wide and indicative of the present scarcity of knowledge.
