During the last two decades, major efforts were conducted to characterize the Cosmic-Ray induced neutron spectra in high-altitude stations under different geomagnetic/altitude conditions. Analyses proposed in this work are based on neutron spectra measurements (four stations: Chacaltaya Cosmic Ray Laboratory, Testa Grigia Research Station, Pic du Midi observatory and Concordia polar station) and transport simulations based on modelling of atmospheric cascades according to primary spectra which only depend on the solar modulation potential. Analyses focused on count rates, fluxes and neutron spectra. Complementary calculations allowed to deduce the solar potential and to assess the dose level. Trends of solar potential values issued from the neutron spectra are quite consistent. The monitoring of the neutron fluxes and the neutron dose rate show seasonal oscillations in the Pic du Midi while the Concordia was not impacted. Analyses show the interest to monitor continuously the neutron spectra in distributed high-altitude stations.
