ABSTRACT. The Antarctic plateau contains the best sites on earth for many forms of astronomy, but none of the
existing bases was selected with astronomy as the primary motivation. In this article, we try to systematically com-
pare the merits of potential observatory sites. We include South Pole, Domes A, C, and F, and also Ridge B (running
northeast from Dome A), and what we call "Ridge A" (running southwest from Dome A). Our analysis combines
satellite data, published results, and atmospheric models, to compare the boundary layer, weather, aurorae, airglow,
precipitable water vapor, thermal sky emission, surface temperature, and the free atmosphere, at each site. We find
