Measurements of the thermal radio emission from all major planets have been reported at millimeter and centimeter wavelengths, and from Jupiter and Saturn at decimeter wavelengths as well. The measured brightness temperatures deduced from these measurements generally exceeds the expected equilibrium temperature calculated from solar heating. The highest temperatures are generally those measured at the longer wavelengths, which are thought to refer to the deeper, presumably hotter layers in the atmosphere. At least for Jupiter and Saturn the high flux measured at infrared wavelengths implies an internal source of heat comparable with solar heating.
