Examples

The notebooks are listed in increasing scope and are read in that order. The three Cabo Verde ones build on each other; example_grid_pset stands on its own and can be read at any point.

• get_data downloads the CMEMS subset the three Cabo Verde notebooks read. Run it once, before them.

• example_grid_pset illustrates the seed grid and flow map structures without any advection.

• cabo_verde_ftle seeds a grid, advects it through CMEMS currents with Parcels, and maps the FTLE.

• cabo_verde_lcs turns the same flow maps into repelling and attracting LCS as strain tensor lines.

• cabo_verde_lcs_evolution advects an extracted LCS as a material curve.

Each notebook is a jupytext triplet. The .py (py:percent) is the source of truth; the .md and .ipynb are generated with jupytext --sync, and the .ipynb is committed executed, so the rendered notebook shows real output. Edit the .py, never the .md or .ipynb.
