Abstract

Temperature profiles of the martian atmosphere have been derived from airborne observations of the 8 April 1976 occultation of ε Geminorum. Within the altitude range from 50 to 90 kilometers, these profiles show peak-to-peak variations of 35°K with a vertical scale of 20 kilometers and represent evidence for strong tides in the martian atmosphere. However, more information is necessary to conclusively rule out a radiative explanation for the temperature variations.
