Short summary
Based on on-site measurements and numerical modelling, we eliminated the electrostatic shielding effect of nearby trees from the atmospheric electric potential gradient (PG) time series recorded at Nagycenk, Hungary, Central Europe, revealing their actual variation between 1962 and 2009. The comparison with PG data from another station in the same region implies that there may have been coherent regional changes in Earth’s atmospheric electric field during the investigated time period.
