ABSTRACT 1391 | POSTER 13
THE DESIGN OF THE CRETE COPERNICUS OCEAN COLOUR SYSTEM VICARIOUS CALIBRATION (OC-SVC) INFRASTRUCTURE
Copernicus is Europe’s Earth observation system. Central to this system are the Sentinel satellites that operationally monitor the planet’s environment including how our climate is changing. Ocean Colour Radiometry (OCR) from Space is an essential climate variable and the main data source for monitoring the status of marine ecosystems at global and regional scales. To ensure the quality of the satellite OCR data it is necessary to implement a System Vicarious Calibration (SVC) based on the best possible fiducial reference measurements. This ideally requires a network of three or more ocean colour calibration buoys, consistent between themselves, and with highly accurate SI-traceable radiometry. Two SVC sites currently in operation are the long-established MOBY site in Hawaii and the newly deployed MarONet site off Western Australia. Feasibility of a third infrastructure in European Seas has been investigated by EUMETSAT in recent years under the long-term Copernicus program. After a series of studies covering requirements definition, preliminary design and optimal location, the Crete site led by HCMR has been selected in 2026. It will therefore be the unique infrastructure of the European Union contributing to the SVC of global OCR data, in particular from the present and next-generation Sentinels. This presentation will detail the engineering design, technical definition, and specifications of the Crete Copernicus OC-SVC infrastructure, highlighting in particular the hyperspectral optics system based on MarONet, as well as the other major components including the calibration system, the data processing system, SI-traceability and uncertainty evaluation, the buoy system, and the atmospheric observatory.
