We report new measurements of the muon spectra and the muon charge ratio at ground level in the momentum range from 200 MeV/c to 120 GeV/c for two different geomagnetic locations. Above 0.9 GeV/c the absolute spectra measured in the two locations are in good agreement and are about 10% to 15% lower than previous experimental results. At lower momenta the data show latitude dependent geomagnetic effects. These observations are important for the understanding of the observed neutrino anomaly.
