The GREENGAGE coordinator, Austrian Institute of Technology (AIT), will discuss our latest project achievements at the EuroGEO Workshop 2024. EuroGEO serves as a regional coordination instrument, aligning and coordinating European activities that support GEO (Group on Earth Observations) initiatives. Alongside national and European policymakers, GEO representatives, and members of the academic and research communities, as well as key players from European flagship programs like Copernicus, DestinE, and various EU-funded projects, we will explore our Observatories and their unique contributions to Earth Observation efforts.
