Marine Monitoring: Verification and Communication of Scientific Quality in Operational Oceanography Products

Marine Monitoring - Verification and communication of the scientific quality of operational oceanography products of the Copernicus Marine Service, focusing on the evaluation, documentation, and improvement of the quality information provided to users. Challenges in uncertainty estimates and forecast skills are highlighted, with ongoing developments for enhancing service quality described.

2. A b s t r a c t Marine Monitoring Verification and communication of the scientific quality of operational oceanography products of the Copernicus Marine Service Isabel Garcia Hermosa1, Charly R gnier1, Marie Drevillon1, Marcos Garcia sotillo2, and Camille Sczcypta3. 1Mercator Ocean International, France (igarciahermosa@mercator-ocean.fr). 2Puertos del Estado, Spain. 3CELAD, France. The Copernicus Marine Environment Monitoring Service (CMEMS) is delivering ocean satellite observations, in situ observations, together with ocean model reanalyzes, analyzes and forecasts from a unique web portal (Le Traon et al, 2019, https://doi.org/10.3389/fmars.2019.00234). Each one of these products is evaluated before its entry into service, and its quality is documented in a Quality Information Document (QUID). This information is complemented by regular quality metrics updates on the CMEMS website. Due to a relatively sparse observation network, in particular in subsurface, it is still a challenge to propose meaningful uncertainty estimates and forecast skills to the operational oceanography user s community. In order to improve, and better target the scientific quality information provided to the various types of CMEMS users, several developments are ongoing which will be described in this presentation.

10. C M E M S , a n s w e r i n g u s e r n e e d s o n P Q Marine Monitoring Produce synthetic overview of PQ (for each product) Produce user friendly scores Higher resolution for error estimates More information on quality flags Add number of (good) observations Explain why some products/datasets may be less validated Add online technical lectures Main PQ working lines Provide error estimates as dataset
