Cyclone‐Anticyclone Asymmetry of Eddy Detection on Gridded Altimetry Product in the Mediterranean Sea

International audienceWe perform an Observing System Simulation Experiment (OSSE), that simulates the satellite sampling and the mapping procedure on the sea surface of the high-resolution model CROCO-MED60v40, to investigate the reliability and the accuracy of the detected eddies. The main result of this study is a strong cyclone-anticyclone asymmetry of the eddy detection on the altimetry products AVISO/CMEMS in the Mediterranean Sea. Large scale cyclones having a characteristic radius larger than the local deformation radius are much less reliable than large scale anticyclones. We estimate, that less than 60
