Dataset problem: CORDEX datasets in a Lambert Conformal coordinate system #1879
Comments
|
After discussing with @zklaus and @Neah-Ko, and considering the cordex domain descriptions, we will store in a json file the values of the domain boundaries as given in the specifications:
We can start by checking how does the boundary domain compare to domain in each dataset, by building a mesh grid and plotting the grid points. It is likely that the model domains will expand beyond the standardised domains, as this is done to avoid issues in the boundaries when running the model With that information, then fixing the grid would be a matter of transforming the lambert and geographical coordinate systems back and forth, whether that is to fix coordinate points or generate the bounds. If relevant, and depending on how the mentioned plots look like, we could consider cropping the cube to fit the standardised domain. |
Describe the dataset issue
PR #1765 fixed datasets that use rotated pole coordinates, but not Lambert conformal ones. I see two possibilities to fix the data:
1- Regrid the lambert conformal datasets to the rotated pole coordinates
2- Take the standardised rlat and rlot coordinates, convert their coordinate system to LambertConformal and interpolate the points to match the shape of the data. For the geographical coordinates, just interpolate to match the shape of the data.
I am not sure if either approach is very precise, so more ideas are welcome.

Assign the right people
If you are already a member of the ESMValTool GitHub project, please assign Valeriu Predoi (valeriupredoi) and
Klaus Zimmermann (zklaus) to the issue. They will then check the issue raised and propagate it further to the
data model developers.
Please attach
