Geomagnetism Data Portal: a new service from the World Data Centre, Edinburgh

Since 2007, the World Data Centre (WDC) for Geomagnetism in Edinburgh has made geomagnetic observatory datasets available via its “Geomagnetic Data Master Catalogue” website. This website is widely used by scientists looking for definitive geomagnetic observatory data, and has served over 1 million requests for data since first opening. Current data holdings span 150 years and 350 observatories. The original website, based on work at the Danish Meteorological Institute, provided a simple catalogue of data showing data availability on a per-observatory basis, and FTP download of data files in WDC format. Useful features such as search, visualization, and delivery of data in other formats were missing. In 2013, work began on replacing this website with one that takes advantage of advances in web technology to provide an enhanced service to users. The new website (the “Geomagnetism Data Portal”) offers the following functionality: * Users may query the data repository using various attributes such as geodetic coordinates, time and cadence, in order to discover data of interest. * Users may create and save plots of datasets or collections of datasets, allowing for quick checking of data quality, etc., without having to first download the data. * Users may download datasets in a number of common data formats, such as WDC, IAGA-2002, ImagCDF, INTERMAGNET BINARY, JSON, XML, and CSV. * All functionality is also available via easy-to-use web services, allowing for direct integration of the Data Portal with software such as Matlab, R, Excel, etc. In this poster we present a tour of the various features provided by the Geomagnetism Data Portal.
