 The present work examines the spatial and temporal distribution of positive and negative total electron content, TC, anomalies on the global and regional scale. Ground ionis on station data and total electron content, TC, data for madrigal and code databases were used to study the local response of the ionosphere. The relative deviation between the two datasets was considered to determine the type of TEC response during geomagnetic storms on the 3rd and 4th of February 2022. The locations of positive and negative TEC anomalies and their evolution during storms were examined in detail. Estimates of the following were obtained, I, the location of the sectors of the polar regions in which the particle precipitation from the solar wind is observed, II, the mid-latitude regions in which the mechanism of influence of the O slash N2 ratio dominates, and III, the region around the equator in which the influence of the electric field dominates. An attempt was made to determine which mechanism of influence of geomagnetic storms on the ionospheric electron density is dominant in different regions. The following main mechanisms were considered, A, the additional ionization. This article was authored by Rumiana Bajilova and Plamen Mukhtarov. We are article.tv, links in the description below.
