Energetic particles effects on the global atmospheric electric circuit
Abstract
Events of Energetic particles are potential candidates to affect the Global Atmospheric Electrical Circuit (GAEC). This is supported by theoretical models proposing that these events can modify the atmospheric conductivity profile above thunderstorms. If very strong events occur, they are able to change the atmospheric conductivity at low altitudes. These effects can be studied through measurements of the atmospheric electric field (AEF) in fair weather regions. In this study, we investigate the AEF daily curve departures from the standard curve during solar proton events and Forbush decrease. The superposed epoch analysis was utilized in order to enhance weak effects. AEF data corresponds to the period between January 2010 - December 2017, and were recorded at Complejo Astronomico El Leoncito (CASLEO) at 2550 masl. The results show possible ionization effects in regions of disturbed and fair weather regions, which alters the GAEC.
