This chapter discusses the structure and composition of the Earth's atmosphere. The Earth's atmosphere is a reservoir of several gases. The gas molecules in this reservoir are continuously exchanged because of the interaction of different sources and sinks. The average time spent in the atmosphere by the molecules of a given gas is called average residence time, or simply residence time. The concept of the residence time gives a good basis for classifying the atmospheric gases.
