This review of atmospheric muons and neutrinos emphasizes the high energy range relevant for backgrounds to highenergy neutrinos of astrophysical origin. After a brief historical introduction, the main distinguishing features of atmospheric ν µ and ν e are discussed, along with the implications of the muon charge ratio for the ν µ /ν µ ratio. Methods to account for effects of the knee in the primary cosmic-ray spectrum and the energy-dependence of hadronic interactions on the neutrino fluxes

A simple numerical/analytic method is proposed for systematic investigation of uncertainties in neutrino fluxes arising from uncertainties in the primary cosmic-ray spectrum/composition and hadronic interactions.
