Palaeomagnetic intensity data: An Achilles heel of solar activity reconstructions
Reconstructions of solar activity prior to AD1600 rely on estimates of the past production rates of cosmogenic radionuclides in the Earth’s atmosphere. These rates are modulated by the strength of the solar magnetic field and the intensity of the Earth’s geomagnetic dipole. One of the largest uncertainties associated with these reconstructions originates from palaeointensity data and to show how e
