两个维京着陆器的每日平均气压显示的时间略多于火星年。由于二氧化碳与极冠的交换而导致的压力季节性变化非常明显，并且在一定程度上与早期的理论结果相矛盾。日常变化是天气尺度高压和低压系统通过的结果，是大气总体环流的重要线索。检测并解释全球沙尘暴对大气环流和压力日变化的影响。
Daily mean atmospheric pressures at the two Viking landers are presented for slightly more than a martian year. The seasonal variation of pressure owing to exchange of CO2 with the polar caps is quite evident and contradicts, in part, earlier theoretical results. Day-to-day variations are the result of passage of synoptic-scale high and low pressure systems and are an important clue to the general circulation of the atmosphere. The effects of global dust storms on the general circulation and on the diurnal variation of pressure are detected and interpreted.
