Impact of L4 SHH Products on Lagrangian Drift Assessed on the EDITO Platform (ILSP-LDAE)
Observe how different L4 mapping products (DUACS, MIOST, VarDyn, 4dVarNet) of SSH affect the dispersion and accuracy of reconstructed trajectory ensembles of ocean surface drifters. Focusing on one ensemble at first and derive statistics from several ensembles if time allows it.
Provide open-source and reproducible comparison pipeline. Easily include additional L4 mapping methods (NeurOST) or lagrangian simulators.
Global Drifter Program ; DUACS, MIOST, VarDyn, 4dVarNet. Uploaded to the EDITO cloud.
OceanParcels: https://github.com/OceanParcels/parcels. And maybe some other simulators.
A few CPUs will be enough when working on a single ensemble, a GPU will be necessary to reconstruct a large number of ensembles.
