CiROCCO’s vision is to establish an end-to-end sensing system, composed of a distributed network of cost-effective sensing nodes coupled with state-of-the-art data fusion remote sensing and assimilation modelling techniques. A mix of wireless communications including satellite, and local Wireless Sensor Networks is used for the collection of data. The defined network of sensors will enhance the current lack of ground observation in desert areas covering Egypt, Serbia and Spain, offering an operational and in parallel easy to maintain and expand solution. Four services are developed i) Renewable energy systems planning ii) Air quality early warning system for human health iii) Land use and ecosystem management iv) Modelling of GHGs and particles emissions, to validate the quality of the collected data and drive the sustainability and exploitation path of the overall system. CiROCCO performance and capabilities will be tested and validated in real-life settings in four large in Cyprus, Egypt, Serbia and Spain. Commercialisation services ensure the sustainability of the installation and in parallel FAIR management of data will support Cross-COPERNICUS ecosystem integration and assimilation services.
