The research activity at the University of Calabria is focused on the Solar-Terrestrial interactions on several timescales (from minutes to years) by considering both dynamic and radiative processes. The research is organized in several issues:
- The study of the dynamic processes consists into the characterization of the magnetospheric response to solar wind changes in both solar quiet and disturbed periods. Particularly, we are involved into the statistical study of the geomagnetic storms, that can be monitored via a set of geomagnetic indices related to the different magnetospheric current systems (Sym-H, AE, AL) and that change accordingly to variations in solar wind parameters (magnetic field, dynamic pressure, solar wind speed) on short timescales (tens to hundreds of minutes).
- We are interested into the relations between the ionosphere and the Solar Quiet (Sq) geomagnetic field and into the production of geomagnetic pulsations (Pc5) at ultra-low frequency (ULF waves), that affect the dynamic properties of electrons in the radiation belts, searching the causes that lead such particles to be accelerated at relativistic speeds.
- We are performing the statistical study of the occurrence of Solar Energetic Particles (SEPs) produced by solar eruptive events such as flares, coronal mass ejections (CMEs) and active regions, and their effects on the Earth’s environment. In particular these particles have a deep impact on our technological society, and probably also on our climate change throughout complex interactions with the Earth’s atmosphere.
- We also focus our research activity on the Earth’s climate with particular reference to the interactions between the incoming solar radiation and the infrared emitted one. For this reason, a modified Daisyworld model is built in order to better understand the different contributions which determine this energy budget, by also taking into account the greenhouse effect which plays a relevant role into the definition of the global surface temperature.
