MESI Data Systems

Science requires a solid database and access to dedicated instruments, laboratories, and data products. GFZ’s Modular Earth Science Infrastructure (MESI) provides essential observations for geosciences. It is thus one backbone of research at GFZ and is also available to users from universities and research institutes. The MESI data systems comprise data centres for geodesy and geophysics. This includes federated data archives with open data and standard programming interfaces, as well as derived products of public interest (earthquake monitor and magnetic activity index Kp).
