论文摘要
使用宇宙学大尺度测量师，我们测量磁盘平均的绝对金星亮度温度为432.3 $ \ pm $ 2.8 k和355.6 $ \ pm $ \ pm $ 1.3 k，分别为38.8和93.7 GHz。在这两个频段中，这些都是迄今为止最精确的测量值。此外，我们观察到两个频段中测得的温度的相位依赖性。我们的测量结果与Co $ _2 $ dominant大气模型一致，该模型包括少数额外的吸收剂，例如$ _2 $和h $ _2 $ so $ _4 $。
Using the Cosmology Large Angular Scale Surveyor, we measure the disk-averaged absolute Venus brightness temperature to be 432.3 $\pm$ 2.8 K and 355.6 $\pm$ 1.3 K in the Q and W frequency bands centered at 38.8 and 93.7 GHz, respectively. At both frequency bands, these are the most precise measurements to date. Furthermore, we observe no phase dependence of the measured temperature in either band. Our measurements are consistent with a CO$_2$-dominant atmospheric model that includes trace amounts of additional absorbers like SO$_2$ and H$_2$SO$_4$.
