Synergetic measurements of the vertical atmospheric field and the total charge density in the presence of dust events are presented through the launches of balloon-borne instrumentation, including a MiniMill electrometer and a space charge sensor, under dust events during the AEOLUS Cal/Val campaign of ASKOS in Cabo Verde, in June/September 2022. The electric field profiling measurements obtained by different instrumentations are compared, and the near-ground observations are evaluated with a reference ground-based fieldmill electrometer. Moreover, their performance is assessed by utilizing measurements of the co-located Polly XT lidar and its extracted products above the launching site. [ABSTRACT FROM AUTHOR]

We present experimental results on the long-term modulation of cosmic rays (CR) related to the solar cycle and on shorter timescale related to the natural radiation from precipitated rain. A preliminary correlation between CR and the amount of precipitated rain water indicates the possible influence of the atmospheric electric field [ABSTRACT FROM AUTHOR]
