Abstract: We examined the mathematical and computational aspects of the magnetic potential, vector and gradient tensor fields of a tesseroid in a geocentric spherical coordinate system (SCS). This ...
From global geopotential coefficient model, calculate the model value of the height anomaly (m), gravity anomaly (mGal), gravity disturbance (mGal), vertical deflection vector (ʺ, south, west), ...
