Thermal physics (and some chemistry) of the atmosphere (S.K. Lower, 11 pages.) An exploration of how the temperature of the atmosphere varies with altitude can serve as a useful means of illustrating some important principles relating to the behavior of gases and to the absorption and transformation of radiant energy.
