Study Summary

This study analyzes the variability of the atmospheric electric field (potential gradient, PG) in Ica, Peru, based on continuous measurements conducted between March 2018 and December 2022. The research focuses on identifying fair weather conditions and characterizing the typical diurnal PG curve for an arid coastal station.

Results indicate that the PG in Ica is strongly modulated by local processes. A wind speed threshold of 3.5 m/s was identified, beyond which the PG exhibits significant perturbations due to the lifting and transport of dust and aerosols. The study also identifies seasonal variability and spectral signals associated with regional and global oscillations.
