Global geomagnetic observatory annual means.

Dataset description

Annual means of the geomagnetic field vector components from observatories around the world, from 1840 to the present day. At present there are about 160 observatories. These data are useful for tracking changes in the magnetic field generated inside the Earth. Data are produced by a number of organisations around the world, including BGS. Data are available in plain text from www.geomag.bgs.ac.uk. This data is connected to other geomagnetic data sets, but can be used without reference to them.

Constraints

In its role as World Data Centre for Geomagnetism (Edinburgh) we make the data available for scientific research. If the data are used in publications and presentations, the data suppliers and this WDC should be acknowledged. For commercial applications of these data, please contact the relevant institute directly.
