In January 2005, members of a Chinese expedition team … were the first humans to visit Dome A on the Antarctic plateau, a site … predicted to be one of the very best astronomical sites on earth. In 2006, the Chinese Center for Antarctic Astronomy (CCAA)…
PLATO is a fully-robotic observatory designed for operation … in Antarctica. It generates its own electricity (about 1kW), heat … (sufficient to keep two 10-foot shipping containers comfortably above … 0◦C when the outside temperature is at −70◦C)…
The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are … very favorable for high spatial resolution astronomy. At Dome C…
The ground layer turbulence at Dome C is the cause for more than 90% of the total turbulence column. While the height … of this layer has been currently measured to be approximately 30m, no long term statistics is available from this part of … the atmosphere.
The unique atmospheric characteristics found at Dome C on the Antarctic plateau offer significant … advantages for the operation of adaptive optics systems.
Recent data have shown that Dome C, on the Antarctic plateau, is an exceptional site for astronomy, with atmospheric conditions superior to those at any existing mid-latitude site. Dome C, however, may not be the best site on the Antarctic plateau for every kind of astronomy.
Profiling the ground layer turbulence for daytime seeing applications using an array of photodiodes has been documented … in literature, in particular by Beckers who coined the term “SHABAR” for the instrument, short for Shadow Band … Ranger.
The Gattini cameras are two site testing instruments for the measurement of optical sky brightness, large area cloud … cover and auroral detection of the night sky above the high altitude Dome C site in Antarctica. The cameras have been in … operation since January 2006.
Abstract. The atmospheric boundary layer contribution to the total … seeing at Dome C is presented in this paper. With a mean of 0.0700, this … is one of the most stable boundary layer encountered.
We present results of daytime site testing at Dome C in summer … 2003-2004. Daytime seeing has been monitored during 2 1 … 2 months … a DIMM on the bright star Canopus, giving median value of 0.54 arcsec. An every-day best seeing period has been observed around 5pm … with seeing around 0.3 arcsec.
We present wind and temperature profiles at Dome C measured … by balloon born sonds during the polar summer. Data from 197 … flights have been processed for 4 campaigns between 2000 and 2004. We show the exceptionnal wind conditions at Dome C, Average ground … wind speed is 3.6 m/s.
Ground layer Adaptive Optics (GLAO) is a new variant of adaptive optics that aims at correcting the seeing … over a wide field of view by conjugating the deformable mirror to the boundary layer altitude.
