Abstract
Abstract. The Széchenyi István Geophysical Observatory, also known as the Nagycenk Geophysical Observatory (NCK), was established in 1957. It has been the only measurement site in Hungary where observations of various parameters of the atmospheric global electric circuit are made in the framework of organized research under the umbrella of the Hungarian Academy of Sciences (MTA). Measurements of the atmospheric electrical potential gradient (PG) and Schumann resonances (SRs) running quasi-continuously in the observatory for decades provide an invaluable source of information for geophysical research. This paper gives an overview on the history of the observatory and particularly on various atmospheric electricity (AE) measurements on-site to commemorate the efforts and excellence of the people who served atmospheric sciences by dedicating their lives to obtaining high-quality, reliable data and scientific achievements at the highest possible level.
Highlights
At that time, the laboratory intended to explore and exploit the usage of the telluric method in geophysical prospecting for raw materials
This paper focuses on those measurements which have been conducted at the Széchenyi István Geophysical Observatory near Nagycenk, Hungary, and are more closely related to research on the global electric circuit (GEC) (Rycroft et al, 2012)
The Széchenyi István Geophysical Observatory has a privileged position within the field of geophysical research in Hungary, hosting the widest range of atmospheric electricity measurements in the country
Summary
The establishment of a geophysical observatory near Sopron, Hungary, had been put forward by Prof Károly Kántás, head of the Geophysical Research Laboratory of the Hungarian Academy of Sciences (MTA). Note that in 1825, Count István Széchenyi, a member of this family, was the proposer and supporter of the establishment of a “learned society” in Hungary that has eventually become the Hungarian Academy of Sciences This is why the observatory has become known as the Nagycenk Geophysical Observatory and has received later the Intermagnet code NCK which is the most often used and widely known abbreviation of the facility to date. This paper focuses on those measurements which have been conducted at the Széchenyi István Geophysical Observatory near Nagycenk, Hungary, and are more closely related to research on the global electric circuit (GEC) (Rycroft et al, 2012). Pre-processed data were disseminated in the series of Geophysical Observatory Reports published by the director of the mother institution of the observatory
