  We report on the disk-averaged absolute brightness temperatures of Venus
measured at four microwave frequency bands with the Cosmology Large Angular
Scale Surveyor (CLASS). We measure temperatures of 432.3 $\pm$ 2.8 K, 355.6
$\pm$ 1.3 K, 317.9 $\pm$ 1.7 K, and 294.7 $\pm$ 1.9 K for frequency bands
centered at 38.8, 93.7, 147.9, and 217.5 GHz, respectively. We do not observe
any dependence of the measured brightness temperatures on solar illumination
for all four frequency bands. A joint analysis of our measurements with lower
frequency Very Large Array (VLA) observations suggests relatively warmer
($\sim$ 7 K higher) mean atmospheric temperatures and lower abundances of
microwave continuum absorbers than those inferred from prior radio occultation
measurements.
