Worldwide geomagnetic data, GIC indices and alert: World Data Center of Geomagnetism (WDC) observatories
========================================================================================================

.. contents:: Table of contents

The mission of the World Data Center for Geomagnetism is to provide geomagnetic field data supplied from a worldwide network of magnetic observatories, as well as geomagnetic indices (AE index, ASY/SYM index, and Dst index) derived in this data center to researchers specializing mostly in solar terrestrial physics, and geomagnetism in order to facilitate the global exchange of the geomagnetic field data including the geomagnetic indices. From the WDC websites it is possible to download 1-minute averages (in daily files) of vector components in either (H, D, Z) or (X, Y, Z) reference frame from world wide magnetic observatories. For this reason, it is not possible to exhaustively fill this form. For instance, the time window of data availability changes from observatory to observatory as well as the tern provided (either (H, D, Z) or (X, Y, Z)) . Data from WDC will be used only for the limited number of events that will be selected, so that a manual selection of the observatories and of the time period will be made. The set of WDC observatories well overlap to the set of INTERMAGNET observatories. WDC data can be retrieved through queries to a web service (http://www.wdc.bgs.ac.uk/dataportal/webservice_doc.html). At the present moment, however, the service and the website are not working properly and it is not possible to download a sample file.
