The main objectives of this study are: analysis of the associated spectrum of the geomagnetic field, time of occurrence of geomagnetic storms and comparisons between recordings made at various geomagnetic observatories in the INTERMAGNET network, in terms of frequency intensity identified and correlations during geomagnetic disturbances.
A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by ejections of solar corona mass, coronal holes or solar flares. The data used in this paper are recorded from the Surlari Observatory, and additional information for the characterization of the analyzed geomagnetic storms, we obtained from specialized sites such as www.intermagnet.org and www.noaa.gov. The information about the geomagnetic data from other observatories, as well as about the planetary physical parameters allowed us to make comparative studies between the data recorded in different observatories. We used and calculated filtered data, spectral analysis, wavelet algorithms with different mathematical functions at different levels, the variation of the correlation coefficients for the magnetic components recorded at different latitudes and longitudes. |
