The World Data Centre for Geomagnetism (WDC) has a comprehensive set of digital geomagnetic data as well as indices of geomagnetic activity supplied from a worldwide network of magnetic observatories.
We are an active WDC engaging with the geomagnetic community to grow our data collections. We send out an annual 'call for data' to operating observatories and work closely with WDS network member INTERMAGNET to ingest data from their associated observatories.
We maintain a list of observatory information on behalf of IAGA Division V - Observatories working group . We aim to improve the metadata associated with observatory data and are working with the geomagnetism community, INTERMAGNET and EPOS to advance this.
We aim to improve the ways in which our data are available by developing web service applications, such as our Data Portal.
