Abstract
This contribution consists of a summary of the detection of structure in the Tenerife data and examines the potential for future ground-base d CMB observations. The Tenerife dec +40 degrees data is presented and compared with the emission from known discrete radio sources. After c orrection for the point source component, a likelihood analysis result s in a multi-frequency detection of structure. The amplitude of the si gnal is compared with the level of CMB anisotropy reported by other ex periments and is also shown to be consistent with the previous 95% upp er limits of Watson et al. (1992). In the light of these results, the prospects for ground-based CMB observations are investigated. Referenc e is made to the preliminary results from the Cambridge Cosmic Anisotr opy Telescope and plans are described for the Very Small Array.
