• Grand minima and maxima of solar activity: new observational constraints (2007, methodology): “…reconstructions, which are based on alternative paleomagnetic models: one which yields an estimate of the virtual aligned dipole moment (VADM) since 9500 BC (Yang et al. 2000), and the other a recent paleomagnetic reconstruction of the true dipole moment since 5000 BC (Korte & Constable 2005).”
• Dynamics of the Laschamp geomagnetic excursion from Black Sea sediments (2012, result): “Although results were doubted because of selfreversal in some parts of the lavas (e.g., Heller and Petersen, 1982; Krása et al., 2005), a summary of various modern studies on these flows yielded consistent and reliable paleomagnetic data (Plenier et al., 2007).”
• PADM2M: a penalized maximum likelihood model of the 0–2 Ma palaeomagnetic axial dipole moment (2011, background): “…spherical harmonic models of Earth’s magnetic field derived from historical, archaeomagnetic and/or palaeomagnetic data (Jackson et al. 2000; Korte & Constable 2005; Korte et al. 2009) have yielded insights into dynamo processes (e.g. Amit & Olson 2006; Dumberry & Finlay 2007; Wardinski &…”
• Geomagnetic field for 0–3 ka: 2. A new series of time‐varying global models (2009, methodology): “On the basis of investigations of present field data and VADMs from model predictions we proposed that about half of the difference can be explained by a systematic bias of the VADMs due to the geographical data distribution [Korte and Constable, 2005b, 2006].”
• Source of oceanic magnetic anomalies and the geomagnetic polarity time scale (2007, background): “Absolute paleointensities from archeomagnetic materials suggest that field intensities at 1–3 ka were approximately 40–50% higher than the present field (Yang et al., 2000) although nondipolar field variations undoubtedly result in considerable spatial variability (Korte and Constable, 2005).”
• Solar activity during the Holocene: the Hallstatt cycle and its consequence for grand minima and maxima (2016, methodology): “To be valid, this “paleomagnetic” approach requires a dual averaging of the data, boh in time and space, to best smooth out non-dipole field components (for a discussion, see, e.g., Korte & Constable 2005; Genevey et al. 2008).”
• Evolution of the solar irradiance during the Holocene (2011, methodology): “…VADM models give results very similar to each other over the full plotted period of time, whereas the VDM models give somewhat higher irradiances, in particular the VDM reconstruction based on Korte & Constable (2005), because of their systematically lower paleomagnetic dipole moment (see Fig.”
• Solar Irradiance Variability and Climate (2013, background): “Hence, if the geomagnetic field is known from a previous reconstruction (e.g. Knudsen et al. 2008, Korte & Constable 2005), then the level of solar activity, primarily modulation potential, which depends mainly on the Sun’s open magnetic flux, can be determined using a simple model.”
• Geomagnetic field for 0–3 ka: 1. New data sets for global modeling (2009, methodology): “The models, although still smooth compared to the actual measurements, have better resolution than CALS7K.2 [Korte and Constable, 2005], as based on the spatial power spectra.”
• Cosmic ray induced ionization in the atmosphere: Full modeling and practical applications (2006, background): “We note that M = 0 would roughly correspond to a reversal of the geomagnetic field, which occurs regularly on the geological timescales [Eide and Torsvik, 1996], while the variations of the dipole moment by a factor of 2 both ways have been observed during the last millennia [Yang et al., 2000; Kor”
• Continuous geomagnetic field models for the past 7 millennia: 2. CALS7K (2005, result): “5) further supports that a large part of the offset might be attributable to this effect, which we study further in a subsequent paper [Korte and Constable, 2004].”
• 9,400 years of cosmic radiation and solar activity from ice cores and tree rings (2012, methodology): “The wavelet coherence between TSI of this study and two other recent TSI reconstructions (22, 25) based on single radionuclide records show agreement in the lowfrequency part (periods longer than 100 y) and differences in the high-frequency part (periods shorter than 100 y) (SI Appendix, Section S13”
• A History of Solar Activity over Millennia (2008, unknown): “An update (Usoskin et al., 2006a) of this result, using a more precise paleo-magnetic reconstruction by Korte and Constable (2005) since 5000 BC, suggests that an increase of solar activity comparable with the modern episode might have taken place around 2000 BC, i.e., around 4 millennia ago.”
