Interpolation error in T/S BDY output? #127

Closed jenjar93 closed 4 days ago

jenjar93 commented 1 year ago

Looks like there might be an interpolation issue in the BDY output.

In the Copernicus BDY example, salinity is unrealistically low at depth but the numbers are still sensible (i.e. not filler values), so maybe something to do with the nearest neighbour interpolation in areas of dynamic topography?

I'm not sure what's happening in the benchmark data. It looks like it's overwriting every other profile with values from a different location? The benchmark data also has the same usually low values at depth, both in T and S.

@jenjar93 could you let me know where the Copernicus example data are. It'll be interesting to run through this and maybe we can have a chat tomorrow at some point. Thanks

@jdha I've put the Copernicus data I used (Oct/Nov for the north Indian Ocean) in /work/jenjar/PyBDY/ and rerun pybdy within that folder so everything is self-contained. Happy to discuss further at some point today.
