The top of the atmosphere has an average temperature of about 300 K (80 °F, 27 °C). Meteorology and atmospheric dynamics. The global pattern of atmospheric circulation on Mars shows many superficial similarities to that of Earth, but the root causes
Mars has a thin atmosphere made up mostly of carbon dioxide, nitrogen, and argon gases. To our eyes, the sky would be hazy and red because of suspended dust instead of the familiar blue tint we see on Earth.
