Modernization of the station for monitoring the Earth's natural electromagnetic field in the VLF range at the Verhnyaya Berezovka Station near Ulan-Ude

Abstract

The station for monitoring the Earth's natural electromagnetic field in the VLF range at the Verkhnyaya Berezovka station was upgraded. A database of continuous measurements of the VLF-pulse flux of the natural electromagnetic field of the Earth (NEMF) in the south of Siberia for the period from March 31, 2008 to the present has been created. An analysis of long-term continuous observations has shown that the daily variations in the NEMF have a stable seasonal course. A high coefficient of interannual correlation of daily variations in the NEMF for the same months of 2008–2022 was established.
