TEMPERATURE REGIME AND THE INFLUENCE OF VOLCANISM ON THE COMPOSITION OF THE MARTIAN ATMOSPHERE

The current extremely thin Martian atmosphere is mainly composed of carbon dioxide. The current average temperature near the surface of Mars is 210 K. At the equator, the surface temperature reaches +30°C at noon in summer and drops to - 153°C at the poles in winter. Diurnal variations in the mid-latitudes exceed 100°C. Currently, the Martian climate is characterized by global dust storms. Seasonal fluctuations are also observed in methane concentrations. The current state of the atmosphere is the result of a continuous process of atmospheric loss over geological time. This emphasizes the dramatic climatic and atmospheric evolution. At an altitude of about 40 km, an ozone layer up to 7 km thick has been found in the atmosphere.
