In this paper, the effects of geomagnetic cutoff and solar modulation separately for upward and downward-going neutrinos of both electron and muon flavor with energies from 200 MeV to 10 GeV were taken account.Abstract:
New calculations of the flux of neutrinos produced by cosmic rays in the atmosphere are reported The authors have taken account of effects of the geomagnetic cutoff and of solar modulation separately for upward- and downward-going neutrinos of both electron and muon flavor with energies from 200 MeV to 10 GeV The geomagnetic cutoff in particular must be handled carefully because it induces behavior very similar to a neutrino oscillation signalread more

TL;DR: In this paper, the Kamiokande detector was used to observe atmospheric neutrino interactions in an exposure of 4.92 kt yr and the observed ratio of single ring μ-events to e-events (μ e ) data ( μ e ) MC = 0.60 +007 −0.06 ( stat. ) ± 0.05 ( syst. ) suggests that the atmospheric vμ/ve ratio is smaller than expected.

TL;DR: A shower-biased sample containing 129 showers and 8 tracks collected in three years from 2010 to 2013 is obtained and consistency with the (fe:fμ:fτ):fτ flavor ratio at Earth commonly expected from the averaged oscillations of neutrinos produced by pion decay in distant astrophysical sources is demonstrated.
