Orbital measurements showed that this dust storm reduced the average temperature of the surface and raised the temperature of the atmosphere of Mars by 30 K. [31] The low density of the Martian atmosphere means that winds of 18 to 22 m/s (65 to 79 km/h) are needed to lift dust from the surface, but since Mars is so dry, the dust can stay in the ...
The atmosphere of Mars is colder than Earth’s owing to the larger distance from the Sun, receiving less solar energy and has a lower effective temperature, which is about 210 K (−63 °C; −82 °F). [2] The average surface emission temperature of Mars is just 215 K (−58 °C; −73 °F), which is comparable to inland Antarctica.
Mars is covered in dry iron oxide dust, has seasonal global dust storms, with a duration of about a month. Mars' average global temperature is −81 °F (−63 °C; 210 K), Earth's average global temperature is 57 °F (14 °C; 287 K). The seasonal Martian polar ice caps are mostly dry ice, frozen carbon dioxide atmosphere (CO 2). [23]

After this NASA Ames Research Center started adding more data to improve the model and gain more insight into Martian weather and climate. Mars climate simulation models date as far back as the Viking missions to Mars. Most Mars climate simulation models were written by individual researchers that were never reused or open-sourced.
There are large variations in surface temperature over space and time on airless or near-airless bodies like Mars, which has daily surface temperature variations of 50–60 K. [18] [19] Because of a relative lack of air to transport or retain heat, significant variations in temperature develop. Assuming the planet radiates as a blackbody (i.e ...

During a year, there are large surface temperature swings on the surface between −78.5 °C (−109.3 °F) to 5.7 °C (42.3 °F) [c] similar to Earth's seasons, as both planets have significant axial tilt, Earth at 23.5 degrees and Mars at 25 degrees. Mars was formed approximately 4.5 billion years ago.
