Description
xnemogcm is an interface to open NEMO ocean global circulation model output dataset and create a xgcm grid. NEMO 3.6, 4.0, and 4.2.0 are tested and supported. It can handle large simulations, is aware of meshgrid files, and makes it easy to handle the netCDF outputs od NEMO.

Unsure/Other (explain below)
-
Explain how and why the package falls under these categories (briefly, 1-2 sentences). Please note any areas you are unsure of:
xnemogcm extracts the NEMO output and adds metadata (+ do some other things as change coordinate names, etc), and produces new xarray datasets. It is thus data processing.
I checked the unsure/Other box as a more specific area is physical oceanography.
- Who is the target audience and what are the scientific applications of this package?
The target audience is anyone working with NEMO outputs and python. The scientific applications are any analyse that one want to do with NEMO outputs.
- Are there other Python packages that accomplish similar things? If so, how does yours differ?
Yes, xorca. My package differs as 1) it is more recent, updated to work with newer versions of NEMO, and 2) it uses a very different method to sort variables on the proper grid point (center, face, etc) (cf https://xgcm.readthedocs.io/en/latest/grids.html). xorca uses hardcoded variables, while xnemogcm uses attributes (either output directly by NEMO, or they can also be given while calling the processing functions).
