High frequency (100 Hz) data from two horizontal induction coils measuring the Earth's magnetic field at the Eskdalemuir Observatory in the United Kingdom. The data covers the...

Hourly and minute means of the geomagnetic field vector components from observatories around the world from, respectively, 1883 and 1969, to the present day. At present there...

The K-index scale summarises geomagnetic activity at an observatory by assigning a code, an integer in the range 0 to 9 (0 being the least active field and 9 the most active...

BGS ran a series of Rubidium Vapour magnetometer stations, mainly in the UK, but also overseas. Data is held on 3 batches of CDs. The largest batch consists of 20CDs containing...

Digital one-minute values of the Geomagnetic field elements from Lerwick, Eskdalemuir and Hartland Observatories. Data are available from 1979 up to the present day. Most data...

The aa index is a simple global geomagnetic activity index, with units of 1 nT (nanotesla), which is produced from the K indices from two approximately antipodal observatories....

Index to the reports of work carried out by the BGS and its precursors. The index was set up in 1988 and has worldwide coverage. These reports cover a wide range of scientific...

Collection of annual publications from the global network of magnetic observatories. They typically contain tabulations of hourly, monthly and annual mean values of the...

Values of the geomagnetic field vector components computed from measurements made on land, at sea and in the air since 1900 all round the world. Repeat station data (collected...

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...

Magnetograms are records of variations in the strength and direction of the Earth’s magnetic field. Historically these magnetograms were recorded on paper using photographic...
