Mesoscale model such as Meso-Nh have proven to be highly reliable in reproducing 3D maps of optical turbulence (see Refs. 1, 2, 3, 4) above mid-latitude astronomical sites. These last years ground-based astronomy has been looking towards Antarctica. Especially its summits and the Internal Continental Plateau where the optical turbulence appears to be confined in a shallow layer close to the icy surface. Preliminary measurements have so far indicated pretty good value for the seeing above 30-35… Expand

Exceptional astronomical seeing conditions above Dome C in Antarctica
TLDR
Observations of the wintertime seeing from Dome C, a high point on the Antarctic plateau at a latitude of 75° S, are reported, and the results are remarkable: the median seeing is 0.27 arcsec, and below 0.15‬arcsec 25 per cent of the time. Expand

Antarctic Boundary Layer Seeing
We have modeled the wintertime boundary-layer seeing over the Antarctic ice sheet and find it to be both strong and ubiquitous. We quantify the relations for both the boundary-layer height and seeingExpand
