GEOFON and GFZ contributions towards democratising DAS data

Since its inception in 1993, the GEOFON program has actively promoted standardisation and openness of data, products and software in seismology, and is thus committed to and ready for Open Science. Although the assessed level of FAIR data management for traditional seismological data has reached a good level, the recent rapid uptake of DAS instruments capable of producing petabytes of data poses challenges to data centre operations and users, hindering the full exploitation of the wealth of DAS data. The contributions of the GEOFON Data Centre and all partners involved to facilitate data access and use are presented through synergetic activities carried out in national and international collaborations, mainly divided into three parts: a) development and provision of technical knowledge ranging from experiment setup to different DAS systems configurations tailored to the specific application; b) development of data management policies, discussions, proposals and (where possible) definition and adoption of new standards; c) development of open software tools and services to facilitate FAIR management of data and products. These contributions are being pursued through two major EU-funded projects, Geo-INQUIRE and SUBMERSE. The former focuses on the development of data management strategies and their exploitation for data generated at selected testbed sites through transnational access activities; the latter poses the additional challenge of real-time data flow and management of multidisciplinary data products. Finally, an outlook on the future seismological data distribution landscape is given, with possible scenarios being considered.
