A new data service from the World Data Centre for Geomagnetism, Edinburgh

The British Geological Survey operates the World Data Centre (WDC) for Geomagnetism, Edinburgh providing access to observatory annual mean values, magnetic survey data and real-time magnetic activity indices online. In 2007 we took over responsibility for further geomagnetic datasets with the transfer of minute and hourly mean data for over 100 observatories from WDC Copenhagen to WDC Edinburgh. We present a summary of our current data service, data holdings and quality control procedures. Furthermore we illustrate how we are developing a new WDC data service using up-to-date web technologies to provide an enhanced data provision for WDC users and establish new data exchange programmes with other World Data Centres.
