EUROPEAN RESEARCH INFRASTRUCTURE ON SOLID EARTH

The portfolio of services

The Geomagnetism community will offer a broad portfolio of "web services". Geomagnetism work under EPOS will also see the creation of a community resource for Geomagnetic Observatory metadata, a system that will support a number of the data services. The metadata system is at the design phase and comments about its suitability are sought from the community.




 

 

Service Description Leading institution
