This product provides the Earth conductivity models for the varying conductivity zones throughout the ten Canadian provinces. The earth conductivity models are derived from a review of published results from magnetotelluric (MT) surveys. NRcan has developed a set of over 70 Earth conductivity models for use in calculating the effect of geomagnetic storms on power systems.
