Understanding a planetary atmosphere requires that we understand a number of linked phenomena including the composition and chemistry, the way in which energy is transported, and the motions (dynamics) of the atmosphere. The composition, chemistry and energy transport are linked because the absorption and emission of energy are controlled by chemicals such as ozone and carbon dioxide that are present in very low concentrations, and these in turn are affected by the chemistry.

了解行星大气层需要我们了解许多相关的现象，包括大气层的组成和化学，能量传输的方式以及大气层的运动（动力学）。 组成，化学和能量传输是相互关联的，因为能量的吸收和排放是由化学物质控制的，如臭氧和二氧化碳，这些化学物质的浓度很低，而这些化学物质又受到化学物质的影响。
