Abstract
The level of solar modulation at different times (related to the solar activity) is a central question of solar and galactic cosmic-ray physics. In the first paper of this series, we have established a correspondence between the uncertainties on ground-based detectors count rates and the parameter Ï (modulation level in the force-field approximation) reconstructed from these count rates. In this second paper, we detail a procedure to obtain a reference Ï time series from neutron monitor data. We show that we can have an unbiased and accurate Ï reconstruction (ÎÏ/Ïâ10%). We also discuss the potential of Bonner spheres spectrometers and muon detectors to provide Ï time series. Two by-products of this calculation are updated Ï values for the cosmic-ray database and a web interface to retrieve and plot Ï from the 50's to today (http://lpsc.in2p3.fr/crdb).
