Abstract
The summary geomagnetic field on the reference field for the regional anomalies is surface of the Earth consists of the follow- the sum of the main geomagnetic field and ing components: the intermediate anomalies. Since the components mentioned above have the F0 = Fm + Fim + Fr + F1 + F (1) different space-spectral characteristics, different methods are used for the analytiwhere cal descriptions. The main geomagnetic field, being the global reference field, is approximated by F0 - the observed geomagnetic field the optimal way as a spherical harmonic Fm - the main geomagnetic field series [1]: Fim - the field of the intermediate anoma- n lies Fr - the field of the regional anomalies X = (g cosm\ + n=i m=O F1 - the field of the local anomalies, - the external geomagnetic field.
