dc.descriptionThe Kamiokande II and IMB data on contained events induced by atmospheric neutrinos exhibit too low a ratio of muons to electrons, which has been interpreted as a possible indication of neutrino oscillations. At the same time, the recent data on upward--going muons in underground detectors have shown no evidence for neutrino oscillations, strongly limiting the allowed region of oscillation parameter space. In this paper we confront different types of neutrino oscillation hypotheses with the experimental results. The matter effects in $ν_μ\leftrightarrow ν_e$ and in $ν_μ\leftrightarrow ν_{sterile}$ oscillations are discussed and shown to affect significantly the upward--going muons.
