“…The SCHA.DI.00 model (PAVóN-CARRASCO et al, 2008) is based on the Spherical Cap Harmonic Analysis technique that was originally presented by HAINES (1985) and applied since to numerous geophysical studies (see Table 2 in TORTA et al, 2006, for a list of references). Although this method has been recently revised by THÉBAULT et al (2006), the numerical problems are difficult to solve when only ground data are used, as in the case of archaeomagnetic data sets.…”

“…The shaded stripes indicate cooling periods as deduced from the advance of the Swiss Alps glaciers (after HOLZHAUSER et al, 2005). Following the definition by GALLET et al (2005), and taking into account the figures for the temporal evolution of the magnetic field direction presented in PAVóN-CARRASCO et al (2008), up to 8 archaeomagnetic jerks can be deduced from this curve. All of these coincide with a cooling period; in more detail, the rising part of each intensity Vol.…”

“…Since they are intended to represent the palaeofield on a global scale, these models are usually too smooth to record rapid changes of the Earth's magnetic field (i.e., archaeomagnetic jerks, GALLET et al, 2005) which could be related to climatic changes. Recently the first directional regional model (SCHA.DI.00) to describe the palaeomagnetic field in Europe was proposed (PAVóN-CARRASCO et al, 2008), which seems to better reproduce the variability of the geomagnetic field over this region for the last 2000 years. The SCHA.DI.00 model was developed using the Spherical Cap Harmonic Analysis (SCHA) technique applied to five of the Bayesian European Palaeosecular Variation Curves (PSVC) (GALLET et al, 2002;SCHNEPP and LANOS, 2005;MARTON and FERENCZ, 2006;GÓ MEZ-PACCARD et al, 2006a andZANANIRI et al, 2007), that are based on archaeomagnetic data.…”

The SCHA.DI.00 directional model for the geomagnetic field in Europe for the last 2000 years (PAVóN-CARRASCO et al., 2008) has been updated by modelling the palaeointensity. This model, SCHA.DI.00, was developed from available Bayesian European Palaeosecular Variation Curves using the regional Spherical Cap Harmonic Analysis technique. The comparison of the palaeosecular variation curves, given by the regional model, with available archaeomagnetic data not used in its development showed an improvement with respect to the fit obtained by global archaeomagnetic models. In this paper advantage is taken of recently published palaeointensity databases to develop a complete (direction and intensity) regional archaeomagnetic model for the last 2000 years valid for the European region: the SCHA.DI.00-F model. Not only does this complete model provide an improvement for example for archaeomagnetic data studies, but it is also shown that this new regional model can be used to study the recently proposed link between the centennial secular variation of the geomagnetic field and climate change. The pattern of the archaeosecular variation of the field intensity obtained by SCHA.DI.00-F seems to verify the hypothesis presented by GALLET et al. (2005) about a possible (causal) connection between changes in the geomagnetic field intensity and in climate parameters, opening the door for more discussions on this challenging subject.

This chapter describes spherical cap harmonic analysis (SCHA) for mapping ionospheric plasma flows measured by the Swarm satellites. In Sect. 9.1, SCHA is introduced as a tool for mapping a variety of one, two, and three-dimensional parameters. Section 9.2 provides a detailed summary of the theory pertaining to SCHA including a discussion of the spherical cap coordinate system, boundary conditions and basis functions, calculation of non-integer degree, and practical considerations. Section 9.3 provides a practical example of SCHA mapping of ionospheric plasma flow for a ground-based data set, and Sect. 9.4 focuses on two-dimensional SCHA mapping of Swarm ion drift measurements both independently and in conjunction with measurements from other instruments.
