Abstract

The very low humidity level the high atmospheric stability and high altitude render the Antarctic Plateau one of the best sites of the world for (sub)millimeter observations. Among the various stations available in Antarctica the French-Italian Concordia sitting on one of the top of the Plateau Dome C is expected to achieve the best sub-millimeter observing conditions available from ground in the world. A winter-over station is under construction and would be available by winter 2006. SUMMIT (SUb-MilliMeter Tipper) a radiometer operating at 350 μm at the site has been installed there in summer 2002-03 and is currently monitoring the submillimeter sky opacity. The instrument is accommodated on the roof of the AASTINO (Automated Astrophysical Site Testing INfant Observatory) a module featuring full automated control and data download capabilities. SUMMIT has been already operating at Dome C in summer 2000-01 and at South Pole during winter 2001 and 2002. New results from Dome C will be presented with an evaluation of the pwv (precipitable water vapor) level at the site. A comparison with data obtained with similar instruments at other site suitable for (sub)millimeter observations (Mauna Kea Chajnantor and South Pole) will be also carried out
