Iaga Workshop 2016

XVIIth IAGA Workshop on Geomagnetic Observatory Instruments, Data acquisition and Processing 

September 4-10, 2016

Royal Meteorological Institute of Belgium, Dourbes Magnetic Observatory


Results of the Instruments Inter-comparison and Checking

Two types of instruments were tested: 

  • Proton precession  magnetometers and 
  • DIflux theodolites.

Geomagnetic observations and instruments


For pratical use and scientific research, Belgium must know the value of continuous variations and the geomagnetic field.This is one case for magnetic declination: it is used to find the direction of north with the compass. This is done using the Magnetic Observatories of Dourbes and Manhay. A complete measure of geomagnetic vector is recorded every minute.

Palaeo- and Archaeomagnetism is the study of geomagnetic field variations during geological and archaeological periods, respectively. Rocks, sediments and baked material acquire a magnetisation during their formation or during cooling from high temperatures. This magnetisation lasts over millions of years (remanent magnetisation) and is aligned parallel to the ambient magnetic field at the time of acquisition.
