Saint Petersburg magnetic observatory: from Voeikovo subdivision to INTERMAGNET certification

Abstract

Abstract. Since June 2012 the Saint Petersburg magnetic observatory is being developed and maintained by two institutions of the Russian Academy of Sciences (RAS) – the Geophysical Center of RAS (GC RAS) and the Saint Petersburg branch of the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation of RAS (IZMIRAN SPb). On 29 April 2016 the application of the Saint Petersburg observatory (IAGA code SPG) for introduction into the INTERMAGNET network was accepted after approval by the experts of the first definitive dataset over 2015, produced by the GC RAS, and on 9 June 2016 the SPG observatory was officially certified. One of the oldest series of magnetic observations, originating in 1834, was resumed in the 21st century, meeting the highest quality standards and all modern technical requirements. In this paper a brief historical and scientific background of the SPG observatory foundation and development is given, the stages of its renovation and upgrade in the 21st century are described, and information on its current state is provided. The first results of the observatory functioning are discussed and geomagnetic variations registered at the SPG observatory are assessed and compared with geomagnetic data from the INTERMAGNET observatories located in the same region.

Development and testing of a portable "noise-meter" for areal magnetic noise survey

“…Elimination of the possible sources of artificial noise is essential for producing the high-accuracy geomagnetic data at operational and developing observatories in Russia and neighbouring countries (e.g., "Saint-Petersburg" (SPG), "Klimovskaya" (KLI), "White Sea" (WSE), "Gyulagarak" (Republic of Armenia), etc. Soloviev et al (2016), Sidorov et al (2017, Gvishiani et al (2018Gvishiani et al ( , 2019).…”

On the feasibility of routine baseline improvement in processing of geomagnetic observatory data

“…Through the efforts of the GC RAS in 2014, it was equipped with the modern magnetometric instrumentation, and in 2016 the first definitive data set for 2015 was produced. These data were accepted by INTERMAG-NET, and the observatory was officially included into the network (Soloviev et al 2015;Sidorov et al 2017). The continuous data recording at the observatory are provided by the following instruments: • FGE 3-axial fluxgate magnetometer (DTU, Denmark) for recording the variations of the EMF components; • GSM-19 scalar magnetometer (Gem Systems, Canada) for recording the modulus of the EMF vector.…”

International project INTERMAGNET and magnetic observatories of Russia: cooperation and progress

“…One of the important objectives of the Center is organization of new observato-/ , 02008 (2018) e3sconf/201 E3S Web of Conferences 62 8620 https://doi.org/10.1051 ries and the upgrading of the existing observatories to the level IMO. Through the efforts of GC RAS a new magnetic observatory "Saint Petersburg" SPG was created in 2012, which in 2016 got the status of the IMO (see [6]).…”
