By the observations of Mariners and Veneras, oxygen atom deficiencies and very low exospheric temperatures were found in the upper atmospheres of Mars and Venus. There are two types of interpretations for these phenomena: photochemical ones (CO3 hypothesis), and dynamical ones. In this paper, the latter point of view is summarized. It was emphasized that the effect of atmospheric mixing due to general circulation and/or eddy diffusion is important for the understanding of the Cytherean and Martian atmospheric phenomena.
