To achieve this, WP13 has 3 main technical tasks, in respect of building EGMODA, ESGI and EMTDAMO. Leader : BGS / Participants : GFZ, FMI Based on existing distributed infrastructures, including: - INTERMAGNET ( ), - WDC-Geomagnetism (Edinburgh; ), - and IMAGE ( ). EGMODA will provide direct and easy access to all relevant magnetic field data and models: Open academic access to geomagnetic data (permanent absolute observatory data, surveys, auroral-zone variometer networks, i.e. non- absolute-level magnetic time series data) Open academic access to geomagnetic models (IGRF, WMM, WDMAM ) Comprehensive data and metadata through a web interface and web services and through direct access to databases. Leader : EOST / Participants : EO, GFZ, FMI Based on existing distributed infrastructures, including: - ISGI ( ), - Service on Rapid Magnetic Variations ( ), - and Service of Kp Index ( ). ESGI will provide direct and easy access to geomagnetic indices and list of remarkable events: Tools (discrimination of quiet or disturbed magnetic periods) & proxies with clear common data formats, Characteristics of geomagnetic activity and space weather conditions (past and in quasi real-time) with comprehensive metadata, through Web interface/services and direct access to databases. Leader : UOULU Participants : Lulea University of Technology, Sweden; IG Magnetotelluric data have not yet been collected on the European level. EMTDAMO is thus a service in implementation. The inventory of existing data will be done jointly with the definition of metadata (survey and instrument information) before any software development. The final aim and benefits will be an evolving website and database that, with metadata, will enable access to magnetotelluric time series (magnetic, electric field), magnetotelluric transfer functions and crustal/lithospheric conductivity models in time (last 30 years) and space (Europe). The task will also provide a computational platform to compile several local conductivity models into a single regional model. In the main, the data, products and services provided through this work package will come from existing international collaborations, hosted by an individual institute (but the product of many institutes around the world). These collaborations are decades old and have proved their sustainability. They are not dependent on the continued participation of any one institute and have show in the past their ability to transfer provision of service from one institute to another at times when an institute is no longer able to continue operating in this area of work. EGMODA European Geomagnetic MOdel and Data Archive ESGI European Service of Geomagnetic Indices EMTDAMO European service of MagnetoTelluric DAta and MOdels A high level analysis shows these items of work to be done within WP13 by month 24: Work with ICS to resolve problems on interfacing initial DDSS elements: o IGRF and WMM (global magnetic models) o Geomagnetism observatory data (WDC & INTERMAGNET) Create a Metadata store for Geomagnetism which interfaces the ICS metadata store Complete the web services for Geomagnetic Index and Event products and interface it to the ICS Create a web service for the Magnetic survey data (WDC) and interface it to the ICS Create a web service for IMAGE variometer data and interface it to the ICS Liaise with the WDMAM authors. Provide access to the WDMAM model via EPOS Work with the Magnetotelluric community to define a data centre for Magnetotelluric data.
