Submillimeter Site Testing at Dome C, Antarctica
We have developed a 350μm radiometer to perform automated site testing in remote regions of Antarctica. In summer 2000–2001 the instrument operated at Concordia, a new station under construction at Dome C on the Antarctic Plateau. We present the results, and compare them with the atmospheric opacity measured at the South Pole in the same five-week period. During these five weeks, observing cond...
متن کاملSite testing Dome A, Antarctica
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 highest point of the plateau is Dome A, some 800 m higher than Dome C. It should experience colder atmospheric tempe...
متن کاملSite testing for submillimetre astronomy at Dome C, Antarctica
Aims. Over the past few years a major effort has been put into the exploration of potential sites for the deployment of submillimetre astronomical facilities. Amongst the most important sites are Dome C and Dome A on the Antarctic Plateau, and the Chajnantor area in Chile. In this context, we report on measurements of the sky opacity at 200 μm over a period of three years at the French-Italian ...
متن کاملPre-HEAT: submillimeter site testing and astronomical spectra from Dome A, Antarctica
Pre-HEAT is a 20 cm aperture submillimeter-wave telescope with a 660 GHz (450 micron) Schottky diode heterodyne receiver and digital FFT spectrometer for the Plateau Observatory (PLATO) developed by the University of New South Wales. In January 2008 it was deployed to Dome A, the summit of the Antarctic plateau, as part of a scientific traverse led by the Polar Research Institute of China and t...
متن کاملDome C — the best astronomical site in the world ?
A decade of site testing at the South Pole has shown that the Antarctic Plateau can offer enormous opportunities for astronomers. The combination of extreme cold and dryness, high altitude and very low wind speeds throughout the troposphere confers powerful advantages—especially for infrared and sub-millimetre astronomy. However, Dome C is higher, drier and colder than South Pole, and has signi...
