Correspondence of EOP and geomagnetic field

Abstract

International audienceConnection of EOP with centred and eccentric geomagnetic dipole fields is described (with the use of Gaussian coefficients) for the epoch 1880-2000. The main tools of statistical investigation carried out were Laplace-type robust estimation (in case of ∆LOD) and the non-linear regression analysis (for P M ). On the basis of computations carried out it can be concluded that the statistical comparison of temporal variation of earth magnetic and EOP data shows significant correlation
