We collect and combine all published data on the vertical atmospheric muon flux and the muon charge ratio for muon momenta above 10 GeV. At sea level the world average of the momentum spectra agrees with the flux calculated by Phys. Rev. D 58 (1998) 054001 within 15 % . The experimental accuracy varies from 7 % at 10 GeV to 13 % at 1 TeV. The ratio of fluxes of positive to negative muons is found to be constant, at a value of 1.268, with relative uncertainties increasing from approximately 1 % at low momenta to about 6 % at 300 GeV.
