Description
In this presentation we want to update on the progress made since the release of the EPOS data portal in 2023.
Research in the geomagnetic and electromagnetic geophysics community have long benefitted from open international exchange of knowledge. Open access to data, models and codes has become increasingly important in a landscape of multi-disciplinary research questions to support societal development. Many countries have developed national research infrastructure, but the need for transnational collaboration requires special effort and innovative approaches.
EPOS, the European Plate Observing System, is a multidisciplinary, distributed research infrastructure that facilitates the integrated use of data, data products, and facilities from the solid Earth science community in Europe. Through EPOS, geomagnetic and electromagnetic data, data products and models are made freely accessible to a wide range of audiences, covering education, stakeholder interests and engagement with policy makers.
While standards and exchange platforms for geomagnetic data and models have long been supported by IAGA committees, the access to magnetotelluric data has until recently been often restricted by missing data standards, repositories and open access policies. Within the EPOS framework, a data- sharing service for MT data has now been developed.
Members of the geomagnetic and EM community in Europe work towards the realisation of not only the data access, but also the delivery of tools and training material to make geo-electromagnetic data usable, following the FAIR principles.
Python based jupyter notebooks are provided by the TCS geomagnetism in order to teach the use of data sources provided by EPOS. The notebook for space weather related analysis shows some simple examples on how to combine data from different sources into joined data structures and diagrams.
This presentation aims to further engage the scientific community on what future developments are required and desirable to engage wider audiences with our science, data and vision.
The depicted example highlights the combination of three data sources, the comparision of local geomagnetic observatory data with global activity indices and (global) event detection information like sudden storm commencements. Such quick data access provides valuable information i.e for validating local event detectors and indices against global, IAGA endorsed standards.
