A collection of methods to generate Lagrangian Coherent Structures
The goal of the package is to make it has easy as possible to calculate Lagrangian Coherent Structures any velocity fields that can be loaded into an xarray datasets. The package consumes and outputs xr.Dataset() and xr.DataArray(), data structures of choice for geoscientists, and uses OceanParcels to efficiently calculate trajectories.
Coming to github very soon! The initial release will include methods to calculate:
- Finite Time Lyapunov exponenent calculation (G. Haller, 2001)
- Lagrangian averaged vorticity deviation (G. Haller, A. Hadjighasem, M. Farazmand, and F. Huhn, 2016)
- Geodesic elliptic material vortices (G. Haller and F.J. Beron-Vera, 2013; , D. Karrasch, F. Huhn, and G. Haller, 2015)
used for the identification of Lagrangian Coherent Eddies in oceanic flows.
