Abstract
We discuss the ultimate limits posed by atmospheric fluctuations to ob servations of cosmic background anisotropies (CBAs) in ground-based an d balloon-borne experiments both in the radio and millimetric regions. We present correlation techniques useful in separating CBAs from atmo spheric fluctuations. An experimental procedure is discussed for testi ng a site in view of possible CBA observations. Four sites with altitu des ranging from 0 up to 3.5 km have been tested.
