Singular value decomposition (SVD) has numerical advantages over other least squares modeling techniques because it requires the summation of basis functions only, rather than of their squares and products. It also transforms the original independent

SUMMARY Secular variation of the geomagnetic field is required in main-field modelling for updating data and for model prediction. In either case, it is differences between field values at two different epochs, at any given location, that is required

[1] A spherical cap harmonic analysis (SCHA) technique is introduced for mapping the 2-D high-latitude ionospheric convection pattern based on Super Dual Auroral Radar Network (SuperDARN) velocity measurements. The current method for generating such

The DGRF/IGRF candidate models have been compared to the Canadian Geomagnetic Reference Field 1990 (CGRF90) over the approximate area of Canada. It is found that all candidate models for 1985 are of equal quality when compared to the CGRF90. For 1990

The choice of basis functions for a given mathematical expansion is critical. It determines whether the expansion is uniformly convergent, whether the expansion can be differentiated termwise, and finally whether this differentiated expansion is unif

Regional models of the earth's magnetic field have developed considerably since the days of hand contouring. They have incorporated varying levels of mathematical sophistication, from partial “mutual consistency” on a surface to full electromagne

A new shipborne magnetic survey data set provides an overview of magnetic trends and patterns over Hudson Bay. Northeasterly trends characterize the northern part of the bay, with indications of several major faults. Northerly trends predominate in t

Two projections are used on many small-scale maps of Canada: a Lambert conformal conic projection south of 80°N and a modified polyconic projection north of 80°N. The inverse of the latter projection is mathematically derived in the present paper.
