Continuous observations of geomagnetic field run by Institute of Geophysics PAS

Jan Reda

Place of work:

- Parent organization: Institute of Geophysics Polish Academy of Sciences (acronym: IGFPAS)

- Head of Research Group for Geomagnetic Observations in Central Geophysical Observatory at Belsk, ~50km south-west of Warsaw

Work interests: - Methodology of geomagnetic observations: absolute measurements, recording of

variation of geomagnetic field, data acquisition for geomagnetic observations, data processing in geomagnetic observatories

- Practical aspects of magnetotelluric soundings

- Geomagnetic activity, e.g. indices of geomagnetic activity

- works in Definitive Data subcommittee of INTERMAGNET program,collection of definitive data and preparation of final compilation of yearly DVD containing data from all INTERMAGNET observatories (chairman of this subcommittee)

Institute of Geophysics PAS – main departments

BELSKSUWAŁKI

Research magnetic pulsations based

on the network of magnetometers located approximately on the magnetic meridian.

One per few months 1sec data

are transmitted to Tihany (MM100 centre)

Belsk - since 2005

Suwałki - since 2007

Close cooperation with Eotvos Lorand Geophysical Institute

Observation in frame of IMAGE network(International Monitor for Auroral Geomagnetic Effects)

HORNSUND

The prime objectives of IMAGE are to study auroral electrojets and moving two-dimensional current systems.

Hornsund since 1993

On average one per month 1sec data are transmitted to Helsinki (IMAGE centre)

Observations of Schumann resonance phenomena Continuous recording of two horizontal elements of

magnetic field and vertical element of electric field in the ELF frequency range

Sampling rate 100Hz

Continuous recording in Belsk and Hornsund

since 2005 and 2004 respectively.

Close cooperation with Geodetic and Geophysical Research Institute Hungarian Academy of Sciences in Sopron
