The evidences of waves in the atmospheres of Venus and Mars

In the last 15 years, distributions of state properties and velocities measured in the atmospheres of Venus and Mars have indicated the presence of waves of varied types occurring from the lower atmosphere to the exosphere. This paper gives an organized picture of observations which indicate and characterize wave phenomena in the Venusian and Martian atmospheres, to illustrate how widely they occur, and to emphasize the probable importance of waves to the dynamics. Some of the Pioneer Venus Probe observations presented have not been previously discussed in the context of waves.
