LONJSKO POLJE GEOMAGNETIC OBSERVATORY

The observatory is located in the area of the Lonjsko Polje Nature Park (central northern part of Croatia), 65 km SE of Zagreb. From 2012 the geomagnetic field intensity and directions are continously recorded at the observatory. Digital data are produced by vector magnetometers: DIDD (Gem systems, Canada), LEMI-018 and LEMI-035 (Lviv Centre of Institute for Space Research, Ukrain). Weekly absolute observations are performed with the Declination-Inclination magnetometer (MinGeo, Hungary) and GSM-19 magnetometer (Gem Systems, Canada). These absolute observations are used for calibration of continuously recording vector magnetometers.

The geomagnetic observatory is part of the INTERMAGNET and EMMA networks. Continuous data exchange is carried out in cooperation with BCMT (France) and MBFSZ (Hungary).
