Through the European Commission's ConnectinGEO project, the European Network of Earth Observation Networks (ENEON) is going to be launched, including space-based, airborne and in-situ observations networks with the goal of enhancing the use of Earth Observations for assessments, forecasts, and predictions of GEOSS SBA topics and Copernicus services. Anyone working with EO data (also in-situ) and willing to participate in the network is welcomed in this session, from existing European networks and Copernicus services providers to SMEs and the EO industry sector.
