A New NRT Mesoscale Eddy Trajectory Atlas on AVISO
Event: 2019 Ocean Surface Topography Science Team Meeting
Session: Science III: Mesoscale and sub-mesoscale oceanography
Presentation type: Type Poster
A new Near Real Time “Mesoscale Eddy Trajectory Atlas" is to be released in 2019 on the AVISO altimetry portal. This dataset will be produced with the "py-eddy-tracker" software in collaboration with E. Mason from IMEDEA, using daily altimetry maps based on the full altimeter constellation (CMEMS SEALEVEL GLO product formerly known as the AVISO all-sat maps). This new algorithm will provide eddy contours and speed profiles. A delayed time method of tracking will also be used in the NRT product. In addition to the locations of detected eddies along their trajectories, the atlas will include additional information about the amplitude, rotational speed, radius, eddy type (cyclonic/anticyclonic), contour, and speed profile, as well as a flag which stores missing detections. Here we present the methodology and assessment results for these new NRT product lines.
