Status of the project

The team has selected an optimal system architecture in response to the user needs linked with the "Marine observations for weather forecast" use case

The initial phase of the project saw the analysis of user and stakeholder Earth Observation (EO) needs and the related technological gaps based upon a comprehensive analysis of the value chain elements in the European EO infrastructure. It leverages on an extensive database (DB) built to support the analysis. The DB has been populated with 63 EO users, 37 explicit needs, the 6 Copernicus services, 95 EO products, 92 measurements, 427 instruments, and 312 missions. The data is based on Copernicus/GMES requirements documents, FP7 and H2020 EO research projects, the CEOS database, the WMO OSCAR database, and contributions by ONION consortium partners. 

A quantitative methodology has been applied to select promising use cases that emerged from the combination of pressing needs and technological gaps. The results section introduces two different assessment perspectives on said use cases. First, an analysis on the technical maturity of the corresponding EO service is provided. Then, radar plots have been used to break down the score of top use cases assessed by the database. Based on this information, the team selected 10 use cases, and, out of those, four "top scoring" ones: 

  • Marine observations for weather forecast
  • Arctic sea-ice monitoring
  • Agricultural hydric stress
  • Fishing pressure monitoring & aquaculture

In order to showcase the end-to-end Onion added value, the team focused on the Marine Weather Forecast use case and selected an optimal architecture meeting the user needs of the use case considered.
