The high Antarctic plateau offers a unique observing environment that is
in many ways intermediate between earth and space. In the infrared, for
example, the sky brightness is typically 10 to 100 times darker than at
"temperate" observatories. The sub-mm transmission is superior to that
measured anywhere else on earth. However, perhaps the most important
feature of Antarctica is the extraordinary stability of the upper
atmosphere, which dramatically reduces scintillation and offers large
gains in astrometric precision. In this presentation we will discuss the
site-testing results to date, the science that can be best be done, and the
technology demonstrators that can best be tested in Antarctica.
1. Introduction
The Antarctic plateau is the coldest and driest place on earth. The highest points are at
elevations above 4,000 metres. The atmosphere above the plateau is extraordinarily
