Interglacials, Milankovitch Cycles, Solar Activity, and Carbon Dioxide
Figure 7
Atmospheric production rate of 10Be as a function of the solar modulation factor and the geomagnetic field intensity . The plot corresponds to (2). The variables are normalized to present values of , , and . Given the 10Be production rate and geomagnetic field from independent records, the normalized solar modulation factor may be calculated for any time in the past.
