abstract = "Solar phenomena such as flares and solar energetic particles
events are potential candidates to affect the global atmospheric
electric circuit. One can study these effects using measurements
of the atmospheric electric field in fair weather regions. In this
paper, we investigate deviations of the atmospheric electric field
daily curve during solar disturbances (solar flares and solar
proton events) from mean values obtained in fair weather
conditions. Using the superposed epoch analysis, in order to
enhance the visualization of small effects, we study the
atmospheric electric field data observed between January 2010 and
December 2015 at the Complejo Astronomico El Leoncito, San Juan,
Argentina. The results show no deviation of the atmospheric
electric field after solar flares, and an increase of about 10 V/m
after solar proton events. The last result suggests possible
ionization effects above thunderstorm in disturbed weather
regions, which alters the global atmospheric electric circuit. On
the other hand, we analyze the variation of the atmospheric
electric field during a ground level enhancement on 17 May 2012,
which was capable to produce changes on the surface electric
field.",
