Abstract
Nearly two centuries ago the first magnetic observatories started to measure the full vector of the Earth’s magnetic field on a continuous basis to provide homogeneous information on its temporal variations. Global coverage of these observatories spread, to enable information to be acquired on the spatial variations of the magnetic field vector and, importantly, on the spatial variations of the temporal variations (and vice versa). Today the global network of magnetic observatories is impressive and the state-of-the-art instrumentation and operations have improved accuracy and resolution. Despite this the community still strive for further increased spatial and temporal resolution. We review the current status of the observatory network, including improvements driven by INTERMAGNET. We look at how the data are being integrated with space-based data and assess how the network fits the needs of the research communities for both the advancement of science and for real world applications.
