English: The primary goals of the presented NASA’s research were to understand the nature of the general circulation of the atmosphere of Mars, how that circulation is driven and how it affects martian long term climate. These studies in turn help us to understand the nature of the martian water, dust and atmospheric pressure cycles. Results of these computer modeling studies also supported numerous Mars missions either underway or under studied. To accomplish this, a number of computer models were used . The simplest of these represents the atmosphere by a vertical column stretching up from the surface to some specified height. This model simulates effects such as atmospheric heating by gases and ground-air heat transfer.
