Sentences with phrase «axial dipole»

We then review recently developed millennial - scale spherical harmonic geomagnetic field models and compare their dipole predictions to virtual axial dipole and virtual geomagnetic pole (VGP) reconstructions, discussing uncertainties in absolute values and variations.

VADMs are obtained by translating archeomagnetic intensity results to the strength of a pure axial dipole field with that intensity at the given geographic latitudes.

Here we review several spherical harmonic models and compare their dipole field predictions to reconstructions based on virtual axial dipole moments and virtual geomagnetic poles.

Methods to scale them to absolute intensities include comparison to globally averaged virtual axial dipole moments (VADM) or to nearby archeomagnetic intensity data.

Not exact matches

So if the C were displaced axially from perfect symmetry, then a dipole moment would exist; and the same goes for any assymmetrical axial momentum for the three atoms, so any change would open the molecule to the 4.0 miron assymmetrical stretch mode which is THE strongest CO2 line, and any displacement or momentum out of the linear cofiguration, will open the moleculae to the 15 micron (667 cm ^ -1) LWIR line that is most active in earth atmosphere.
