Summary

The effects of molecular viscosity and thermal conduction are evaluated by approximate theoretical means, for two atmospheric gravity waves whose properties at low altitudes are taken from two travelling ionospheric disturbances observed by THOME (1964). It is found that the theoretical vertical variations of amplitude and phase are closely comparable to the observed variations, and it is therefore suggested that the latter are strongly controlled by the molecular dissipation processes.
