Geomagnetic Data Service

Data Usage Rules

The rules for the data use and exchange are defined by the International Council for Science - World Data System (ICSU-WDS) Data Sharing Principles. The data and services at the WDC Kyoto are available for scientific use without restrictions, but for the real-time (quicklook) data, please contact our staff (wdc-service@kugi.kyoto-u.ac.jp) before using those in publications and presentations. The WDC Kyoto does not allow commercial applications of the geomagnetic indices.

For commercial applications of the geomagnetic data provided by each observatory, please contact the relevant institute. Information on the institution is supplied within the data sets. When the data are used in publications and presentations, the data suppliers and the WDC for Geomagnetism, Kyoto should be acknowledged. Furthermore, when using the AE index, Dst index, and ASY/SYM indices, please include data DOIs in the Reference section. Rules of the road.
