Radiometry for Ocean Colour Satellites Calibration & Community Engagement
The Copernicus/Sentinels programme places Europe in a world leading position for the delivery of long-term, high-quality, global satellite Ocean Colour Radiometry (OCR) observations. For European institutions involved in delivering Copernicus, both in research and operational fields, data quality is of paramount importance for the success of this program. In particular, the Sentinel-3 satellite series provides Ocean Colour Radiometry (OCR) data to the Copernicus Marine Environment Monitoring Service, CMEMS. The corresponding user products derive from data processing of marine water leaving radiance and reflectance. This is why Ocean Colour “System Vicarious Calibration” (OC-SVC), which allows uncertainties of these variables to stay within required specifications, is of upmost importance. EUMETSAT, a Copernicus operator in charge of the S3/OLCI marine ground segment, envisions having an SVC infrastructure deployed and operated, which meets high technical and operational expectations to reach the expected data quality level. EUMETSAT has defined several steps to reach this objective.
Step 1 was a study aiming at specifying the requirements for such an OC-SVC infrastructure, and completed in 2017. The outputs of this Step 1 form the basis of the present 1-year study called “Step 2”, which should consist in:
Proposing a preliminary design for an OC-SVC infrastructure meeting the Step 1 requirements, including:
