The project complements supporting actionsand networking activities with practical challenges to test and improve the procedures and methods for identifyingobservation data gaps, and to ensure viability in real world scenarios. We present a challenge on future conceptsfor building a data sharing portal for the solar energy industry as well as the state of the art in the domain.Decision makers and project developers of solar power plants have identified the Surface Solar Irradiance(SSI) and its components as an important factor for their business development. SSI observations are crucialin the process of selecting suitable locations for building new plants. Since in-situ pyranometric stations forma sparse network, the search for locations starts with global satellite data and is followed by the deployment ofin-situ sensors in selected areas for at least one year. To form a convincing picture, answers must be sought inthe conjunction of these EO systems, and although companies collecting SSI observations are willing to sharethis information, the means to exchange in-situ measurements across companies and between stakeholders in themarket are still missing.We present a solution for interoperable exchange of SSI data comprising in-situ time-series observations aswell as sensor descriptions based on practical experiences from other domains. More concretely, we willapply concepts and implementations of the Sensor Web Enablement (SWE) framework of the Open GeospatialConsortium (OGC). The work is based on an existing spatial data infrastructure (SDI), which currently comprisesmetadata, maps and coverage data, but no in-situ observations yet. This catalogue is already registered in theGEOSS Common Infrastructure (GCI).We describe the challenges and approach to introduce a suite of standards and best practices into the GEOEnergy Societal Benefit Area for solar radiation measurements. Challenges range from spatio-temporal coverageacross different scales and data quality to intellectual property rights and existing terminology. The approachincludes means to share observations based on standardized data and metadata models and a user-friendly dataexploration/management tool.The possibility to access and share data considerably improves the information base for strategic planningand control of new solar power resources. The platform will be integrated as a new component into theWebservice-Energy.org GEOSS Community Portal dedicated to Energy and Environment. The ability to provideusers with visualisation and download features for in-situ measurements is seen as a key aspect to start engagingthe energy community to share, release and integrate more in-situ measurements. This will put to the test thecapacity of cooperation in the SSI community by introducing an unprecedented level of collaboration andeventually help to detect gaps in European earth observation networks. The presentation will be an opportunity toseek further collaboration partners and feedback by the community.
