It was shown that both experimental and computed records have appreciable divergences. The secular trends of many model curves are flatter than that of the measured record and the difference in amplitude of the century-scale cycle of Gleissberg is highly significant (p<5.5\u00d710-4). Possible causes of this discrepancy are discussed. The obtained results show that at present the cosmogenic isotope data likely contain mostly qualitative information about the behavior of the cosmic ray flux in the past and not always are suited for quantitative estimations.”<\/p>\n","protected":false},"excerpt":{"rendered":"
