Comparisons of proposed and adopted geomagnetic reference field models are made against North American test data for the period 1965 to 1985. These test data...
Annual mean values of the north (X), east (Y) and vertical (Z) components of the magnetic field from 20 observatories in Canada and adjacent countries for the...
A comparison with the International Geomagnetic Reference Field for 1975 (IGRF 1975) of annual mean values in X, Y and Z from 130 magnetic observatories,...
Three methods are used to determine a 1975 position for the north magnetic dip pole. A cubic polynomial in the horizontal components X (north) and Y (east) is...
Approximately 51 000 observations made between 1955 and 1973 were used to produce the magnetic charts of Canada for 1975. A least-square method was used to...
