[ecco-support] [EXTERNAL] Map for each ECCO LLC90 tiles

[Wang, Ou (US 329B)]

Hello Ashfaq,

You can use Cartopy to create more beautiful plots with a projection, similar to the example of using the Polar Stereographic Projection provided in the ECCO v4-py tutorial (https://ecco-v4-python-tutorial.readthedocs.io/ECCO_v4_Plotting_Tiles.html#Polar-Stereographic-Projection).

The Python package ECCOv4-py includes a function named plot_proj_to_latlon_grid (https://github.com/ECCO-GROUP/ECCOv4-py/blob/master/ecco_v4_py/tile_plot_proj.py), which allows you to generate a projected plot. This function first maps the input field from the native model grid to a latitude-longitude grid. Subsequently, it uses Cartopy to create a plot with a user-selected projection from a list of available options, including the Polar Stereographic Projection.

Best,
Ou Wang

Hi!

Can anyone please assist me with the maps that we use for the tiles in the LLC90 output? I am asking it to make my plots look better by adding definite borders/coastlines.

For example, if you look at the tile 6 (image courtesy - link<https://urldefense.us/v3/__https:/ecco-v4-python-tutorial.readthedocs.io/ECCO_v4_Interpolating_Fields_to_LatLon_Grid.html__;!!PvBDto6Hs4WbVuu7!KUgeFhUrQFn8NUC8WT4ADFi-KT_4jfioYr7ndFvVeEoSWcSF6dTsP7qjlJSb65w-f9ldRdfPNW02jn_YdATGPKvAg2uS$>) here -

and if I plot the salinity profile, then I can see figures like this -

I was wondering if I would be able to plot a more defined Arctic border on top of my figure here :)


Sincerely,
