Long-term decreases found recently in both the atmospheric electrical potential gradient (PG) and the air-Earth current density (Jz), using observation series from the UK and Hungary, have motivated studies of other European data. Two surface data

The Nagycenk Geophysical Observatory in Hungary (47° 38 ' N, 16° 43 ' E) has made continuous measurements of the vertical atmospheric electric Potential Gradient (PG) since 1962. Global signals have previously been identified in the Nagycenk

Simultaneous whistler records of one station and geomagnetic pulsation (Pc3) records at three stations were compared. In a previous study correlation was found between occurrence and L value of propagation/excitation for the two phenomena. The rec

The present study is based on simultaneous measurements of the atmospheric electric potential gradient (PG) and Schumann resonances at Nagycenk station (Hungary) from 1993 to 1996. Annual and semi-annual variations detected previously in the relat

Based on continuous measurements of the atmospheric electric potential gradient (PG) in the Geophysical Observatory at Nagycenk (Hungary), selected data of the interval 1993–2003 have been analysed. The analyses were particularly aimed at the confi
