Geomagnetic Observations



The monitoring of Geomagnetic fields has a long history across Europe, though there has been little European-level coordination. EPOS will consolidate the community; modernise data archival and distribution formats for existing services, such as INTERMAGNET; and create new services for magnetotelluric data and geomagnetic models. 




  • Enhance existing services providing geomagnetic data  such as INTERMAGNET (INTErnational Real-time MAGnetic observatory NETwork); the World Data Centre for Geomagnetism; IMAGE (International Monitor for Auroral Geomagnetic Effects) and existing services providing geomagnetic indices such as ISGI (International Service of Geomagnetic Indices);
  • Develop and build access to magnetotelluric (MT) data including transfer functions (TFs) and time series (TSs) data from temporary, portable MT-arrays in Europe, and lithospheric conductivity models derived from TM-data;
  • Develop common web and database access points to global and regional geomagnetic field and conductivity models;
  • Establish links from the WP data services, products and models to the Integrated Core Services.


Our services ready for 2019

  • Virtual Access to data/products/services relying on existing organizations: (INTERMAGNET, WDCG, IMAGE, ISGI)

  • Magnetotelluric data; geomagnetic data from magnetic networks; airborne and shipborne magnetic surveys; auroral zone variometer networks (Level 0, 1) 
  • Global and regional geomagnetic field and conductivity models (Level 2, 3)
  • Characterisation of geomagnetic activity and space weather conditions
  • Virtual Access to computational platform/s 
  • Access for the compilation of lithospheric conductivity models
