Abstract

We discuss the possibility to observe matter effects in atmospheric neutrino oscillations. The main conclusion is that an impact on the nu_mu survival probability requires the action of the MSW resonance, which becomes visible for baselines above ~7000 km. The associated muon charge asymmetry carries information on theta₁₃ and the sign of Dm²₃₁.
