Astronomical seeing from the summits of the Antarctic Plateau
Abstract. From the South Pole, microthermal turbulence within a narrow surface boundary layer some 200m thick provides the dominant contribution to the astronomical seeing. We present results for the seeing at a wavelength of 2.4µm. The narrow turbulence layer above the site, confined close to the s...
