WebNov 15, 2012 · Each year the atmosphere grows and shrinks by about 30 percent due to this effect. The curves also show a strong daily variation in pressure of around 10 percent, with a peak near 7 a.m. on Mars and a minimum near 4 p.m. Web4-1, we have listed all surface average values for both Mars and Earth. From Table 4-1, we can see that the Martian surface atmospheric pressure is only about 6/1000 of Earth’s pressure. The Martian atmospheric average molar weight (gram/mole) is larger than at Earth’s because the dominant gas, CO2, has a larger mass than N2 at Earth ...
