The Open-Earth-Monitor project aims to build a F.A.I.R.-compliant cyberinfrastructure to accelerate the uptake of environmental information and help build user communities at European and global levels. Carson Ross, Project Manager, introduces the project by breaking the name down into its parts: Open, in support of open-science initiatives for the co-development of reproducible products; Earth-Monitor, the tools being created to track and monitor various environmental indicators; and Cyberinfrastructure, which is an ecosystem of actors creating and using data tools in support of the sustainable environmental policy. Funded by the Horizon-Europe programme of the European Commission, a consortium of 23 partners led by the OpenGeoHub foundation will provide operational solutions and decision-making tools for European and global initiatives such as DestinE, Digital Twin Initiative, Fit for 55, UN sustainable development goals and more.
