Federated data space
CLEAR-EO builds a federated data space that provides scalable data governance component for the project to be fully integrated with the internal and external resources in terms of data, applications, computational resources and European data ecosystems.
The Data Space, is designed to implement a central governance of federated and harmonized resources. The objective is to provide the applications developed within the project with unified access to data, avoiding duplication and redundancies.
Computational resources
The CLEAR-EO infrastructure is distributed and heterogeneous, combining cloud, HPC, and on-premise/private facilities, while remaining sovereign by relying exclusively on EU cloud providers. It delivers both compute power for analysis pipelines and storage for temporary data and results, and hosts the development version of CLEAR-EO services as a stepping stone toward full operationalization.
Geo-spatial notification system
The CLEAR-EO Virtual Observatory is a digital platform for application triggering and orchestration, bridging diverse data sources with real-world applications. It runs innovative processing chains — covering phenomena such as rainfall and drought — brokers geo-fenced notifications of relevant events, and triggers downstream applications on demand. The goal is to deliver timely, actionable alerts to both developers and end users, ultimately supporting faster and better-informed decision-making.
AVISO is the geo-spatial notification system at the heart of the CLEAR-EO Virtual Observatory. It notifies users when relevant events occur, orchestrates downstream modelling, and will be extended to support geo-localized event alerts. The system follows a producer–consumer model: producers post notifications specifying the event type and the affected geographic area, while consumers subscribe to event categories within regions of interest and can integrate the client either as a library or a standalone process capable of scheduling further workflows.
