The operating principle of atmospheric Rayleigh LIDAR (light … detection and ranging) systems is that the range-corrected return backscatter … signal is directly related to atmospheric density.
An overview of the meteorological conditions that have a strong influence on the year-to-year … variations in Antarctic ozone depletion is presented.
We present a proposal for an 8.4 metre off-axis optical/IR telescope to be located at Dome C, Antarctica. LAPCAT will use a mirror identical to the offset segment recently cast for the Giant Magellan Telescope (GMT) as a completely unobscured f/2.1 primary.
We describe a large-angle survey for fast, optical transients: gamma ray bursts (GRBs), supernovae (SNe), lensed and … transiting planets, AGNs and serendipitously found objects.
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.
The brightness of the night sky at an astronomical site is one of the principal factors that determine the quality … of available optical observing time. At any site the optical night sky is always brightened with airglow, zodiacal … light, integrated starlight…
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.
