Mars, Jupiter, Saturn, and Uranus: 3.3 -mm Brightness Temperatures and a Search for Variations with Time or Phase Angle.

Abstract

Extensive 3.3-mm observations yield disk-average brightness temperatures for Mars, Jupiter, Saturn, and Uranus. The values for the first three planets are corrected to heliocentric distances of 1.524, 5.203, and 9.540 a.u., respectively. Any variation of the temperature of Mars with phase angle is less than a few percent; this upper limit is consistent with an expected variation of about or less than 3 percent. The measurements from mid-1965 to November 1969 contain no confirmed variations in the brightness temperatures of Jupiter and Saturn larger than approximately 4 and approximately 7 percent, respectively.
