Description
The level of solar modulation phi at different times (related to the solar activity) is a central question of solar and galactic cosmic-ray physics. We detail a procedure to obtain a reference time series from neutron monitor data. We obtain an unbiased and accurate reconstruction at a precision of 10%. Reconstructed time series from the 50's are compared to the previous time-series of Usoskin et al., and to phi values extracted from direct CR flux experiments. An on-line application is available at http://lpsc.in2p3.fr/crdb to retrieve phi values from any period.
