Welcome
Whether you are a scientist, a professional in industry/services or just a curious lay(wo)man, we wish to extend our most warm welcome to you and hope you will have a pleasant visit to this WEB site about Geomagnetic Observatories.

What is a Geomagnetic Observatory?
A Geomagnetic Observatory is a place where the geomagnetic vector has been observed for an extended period of time.By extended period, we understand a duration of at least one full year. The sampling of the field should be 1/hour or faster, with 1/minute becoming standard now.
As only the natural geomagnetic field is of interest here, the Observatory should be protected from artificial magnetic signals, and its surroundings and facilities should be amagnetic, that is, should not modify the direction or amplitude of the geomagnetic vector.
The observations must be fully traceable to metrological standards. Angular measurements should be referenced to the Vertical and to geographic North.

How is the Geomagnetic Field Observed?
We use magnetometers to observe and measure the field. The old magnetometers consist of suspended magnets and magnetic balances registering on photographic paper but the tendency is now to use fluxgate sensors and proton or optically pumped magnetometers with a digital data acquisition system.
Usually a set of variometers will measure the variation of the field components about baseline values. Absolute measurements with the adequate instrumentation (DIfluxes, proton magnetometers) are regularly performed to establish the values of the baselines.
For describing the geomagnetic vector, we need 3 simultaneous measurements for each sample. Depending on the coordinate frame where the vector is described we get the 3 most popular magnetometer orientations:
cartesian:
X(North component), Y(East component), Z (vertical component, positive downwards)
cylindrical:
D (magnetic declination, positive East), H (horizontal component), Z
spherical:
D, I (magnetic inclination, positive downwards), F (magnetic field modulus).
Observers are striving to make measurements with an accuracy of 0.1nT and 1 second of arc. Full information about geomagnetic observations can be found in reference 1.

What is the Output from a Geomagnetic Observatory?
Time series of the field's components are the main output. The series are in the form of second, minute, hourly, daily, monthly or yearly means. They are published in yearbooks, are archived in the Observatories databases and in World Data Centers (WDC). Activity indices are another output. They are available at the observatory or at ISGI. A majority of Observatories are now pertaining to the INTERMAGNET network and have their data accessible in near real time.

Commercial Products and Services by Geomagnetic Observatories
We give here a non-exhaustive list of products and services which may be supplied by your national Observatory. If your country has no Observatory, you may whish to contact one in a neighbouring country. A contact list for observatories is available here.
Products:
Value of the magnetic declination (also abusively called "magnetic variation") for various epochs and/or locations. Users are topographic and cartographic services, oil & gas companies, harbours, air traffic services, airports, military.
Value of the secular variation of the magnetic declination. Users: topographic and cartographic services.
Magnetic charts. Users: Topography, aeronautical mapping and safety services, maritime coastal and fluvial mapping, military.
Time series of geomagnetic field. Users: Aeromagnetic and marine surveyors. High precision directional drilling for gas and oil, Earth orbiting satellite safety, space weather, military.
Services:
High precision in situ measurements of the magnetic declination or other components.
Set-up and certification of compass roses (aircraft compass calibration and compensation facility) in airports.
Measurement of magnetic orientation of aircraft runways.
Measurement of magnetic signatures of mechanical or electronic components.
Calibration and check of magnetic compasses.
Measurement of gyrotheodolites constants

Standards
The total force and the components of the geomagnetic field are a magnetic induction and are therefore expressed in Tesla [T] inside the SI system.The magnetic induction B in the Earth range of 10 microT to 100 microT is conveniently measured by the proton magnetometer. Here the free precession frequency f of protons is the observable and the formula:
2
pf = g 'p B
allows the measurement of the magnetic induction by way of the measurement of a frequency. Our standard for the magnetic induction is thus conveniently converted to a frequency standard, which is widely available.The quantity
g'p is the proton gyromagnetic ratio at low field for a spherical H2O sample at 25 degrees Celsius. The recommended value by the Committee on Data for Science and Technology (CODATA) of the International Council for Scientific Unions is (ref.2):
g 'p = 2.67515255 108 T-1s-1
This value was adopted by this IAGA Working Group on August 19th, 1991 during the IUGG General Assembly in Vienna and recommended for use beginning with the year 1992. This Working Group then also decided to adopt any refinement in this value as anounced by Codata. Prior to 1992, the value of
g'p based on a IAGA resolution from the General Assembly at Helsinki in 1960. All magnetic data produced and published before 1992 are based on this previous value:
g 'p = 2.67513 108 T-1s-1

Helping Geomagnetic Observatories
Many Observatories have chronic difficulties of staff and funding. Their research is based on high quality but nevertheless routine observation. In the competitive environment of scientific funding agencies, it is increasingly difficult to find commitment for support of very-long-term operation. Therefore we welcome any help which could specifically support Geomagnetic Observatories to maintain  and improve their infrastructure and avoid their closing.
Instrumentation pool. Dourbes Observatory is presently maintaining a geomagnetic instrument pool to help Observatories in need of renewed instrumentation (contact: Instrument Pool, IRM-CPG, B-5670 Dourbes, Belgium).The pool has been constituted by transformed, reconditioned and calibrated magnetometers such as proton mags and DIfluxes donated by better-off Institutions. To replenish the rapidly decreasing available pool, we urge the geomagnetic community to continue supply Dourbes with non-magnetic theodolites, fluxgate sensors, digital variometers and proton magnetometers for which they have no use.
