OBJECTIVES / ACTIVITIES

The proposed research aims at achieving an understanding of the space weather effects on conducting structures inside the Earth and on the surface electric field, with applications to a better knowledge of the internal structure of the Earth at continental (Europe) and country scales, on one hand, and to estimating the geophysical hazard of space weather at midlatitudes, on the other.

- To derive the magnetic and electrical properties of the terrestrial lithosphere and mantle at continental and Romanian territory scales;

- To analyze solar eruptive processes and solar wind components responsible for geomagnetic hazardeous activity (geomagnetic storms and substorms) in the time interval 1964-2014;

- To model the geoelectrical field at the Earth’s surface as produced by various magnetospheric and ionospheric current systems;

- To evaluate the geophysical hazard for technological networks, associated to variations of the geolectric field during geomagnetic disturbances linked to the interaction of coronal mass ejections and high speed solar streams with the magnetosphere.
