Principal component analysis as a tool to extract Sq variation from the geomagnetic field observations: conditions of applicability
Anna Morozova, Rania Rebbah
In this paper, we analyze the applicability of the principal component analysis (PCA) as a tool to extract the Sq variation of the geomagnetic field. We tested different geomagneti…

Comparison of the solar variations of the geomagnetic field at the Coimbra Magnetic Observatory (COI) obtained by different methods: effect of the solar and geomagnetic activity
Anna Morozova, Rania Rebbah
Here we present the results of the comparative analysis of the regular daily variations of the geomagnetic field, Sq and SD, obtained from the observations with two methods: (1) us…
