know a little about the martian atmosphere. The atmosphere is 95.3% CO2 with 2.7% nitrogen and 1.6% argon. ("Mars Atmosphere and the Search for Life" Internet). This is similar to Venus's atmosphere. The atmosphere is very thin and because of that, the temperatures on Mars vary widely on a daily basis. The covecting troposhere layer varies with location and season also. At night, it practically disappears because the atmosphere becomes very stable. A typical day of weather on Mars would be something like this: light winds from the east in late afternoon, changing to light winds from the southeast after midnight. The maximum winds would be around 15 mph. The temperatures would range from -122F just after dawn to a maximum of -22F and the Pressure would be steady at about 7.7 millibars ("Mars Atmosphere and the Search for Life" Internet). This is what it would be like on Mars most days. Mars also has clouds. Three different kinds have been located so far. First, one is dust clouds which are raised by winds mainly in the summer time ("Mars Atmosphere and the Search for Life" Internet). The second kind of cloud is ice-water clouds and the third kind is CO2 clouds which form a high altitude haze of dry ice crystals ("Mars Atmosphere and the Search for Life" Internet). If believable, the atmosphere on Mars is much clearer than on Earth, except when Mars is having a major dust storm. Atmosphere pressure on Mars can vary up to 20% with the seasons ("Mars Atmosphere and the Search for Life" Internet). Mars is absent of one main thing and that is water. Due to the low pressure, as well as low temperatures the atmosphere can hold very little water vapor. But, with the pressure and temperature as low as it is, it holds about the maximum that is allowed. Humidity on Mars is very large and because of this, it is common to see water vapor fog forming at low elevations at night. One of the main reasons Mars does not have liquid ...
