The Magnetic Field of Planet Earth (2010, methodology): “Early archeomagnetic field models were built as a sequence of snapshots and restricted to only the first few degrees of the field (Hongre et al. 1998) and next to somewhat higher degrees (by introducing some spatial regularization, Constable et al. 2000).”
Time variations in geomagnetic intensity (2003, background): “Pacific [Constable et al., 2000; Elmaleh et al., 2001].”
The time-averaged magnetic field in numerical dynamos with non-uniform boundary heat flow (2002, background): “Secondly, there is a growing body of evidence from palaeomagnetic directions and intensities for deviations from axisymmetry in the 0–5 Ma palaeomagnetic field (Johnson & Constable 1995, 1997; Kelly & Gubbins 1997; Constable et al. 2000; Kono et al. 2000).”
Improving geomagnetic field reconstructions for 0–3 ka (2011, background): “…axial dipole strength, but also the dipole tilt and further large scale regional6 field variations on millennial timescales (Johnson and Constable, 1998; Hongre et al., 1998;7 Constable et al., 2000; Korte and Constable, 2003, 2005; Valet et al., 2008; Korte et al.,8 2009; Nilsson et al., 2010).”
Continuous geomagnetic field models for the past 7 millennia: 1. A new global data compilation (2005, background): “0 [Constable et al., 2000; Lund and Constable, manuscript in preparation, 2005], which are the basis for CALS3K.1 have also been added to the plots at locations for which they exist.”
Geomagnetic field for 0–3 ka: 2. A new series of time‐varying global models (2009, methodology): “Starting with a series of snapshot models [Constable et al., 2000], the spherical harmonic descriptions were expanded to higher degrees, with regularization techniques used to suppress spurious structure.”
Intensity of the geomagnetic field in western Europe over the past 2000 years: New data from ancient French pottery (2002, background): “[3] However, possibilities for long-lasting, drifting or standing, nondipole features at timescales of several centuries up to amillion years are still strongly debated [e.g.,Courtillot and Le Mouël, 1988; Merrill et al., 1996; Carlut and Courtillot, 1998; Constable et al., 2000].”
Continuous geomagnetic field models for the past 7 millennia: 2. CALS7K (2005, methodology): “This is in fact quite an interesting example: In the interval between 2000 BC and 100 AD the model prediction is still close to that of CALS3K.1, for which an adjusted age scale for Lake Baikal data had been used [Constable et al., 2000].”
