説明
<jats:p>Images of the thermal infrared emission from 10.6 to 12.6 µm from the earth‐facing hemisphere of Venus were made from earth on each available opportunity over a 26‐day period in 1977 and a 106‐day period in 1978–1979, using a 1.5 m telescope. Compact, variable thermal features exist at latitudes higher than about 50°, some of which repeat at 5‐day intervals. No such repeatability is observed for features near the equator. Day‐to‐day variations in limb darkening and the contrast of high latitude features appear to differ in the conjunction and post‐conjunction images. A strong, solar‐fixed component of the emission exists and exhibits wave number 1, 2, and 4 components. The thermal tides provide constraints upon the atmosphere structure. The solar‐fixed structure shows significant asymmetries with respect to the equator.</jats:p>
