Can I use ROMS forcing files directly to run simulation in CROCO?

asked 2020-10-28 05:21:23 +0100

I am currently working on a project which uses ROMS (myroms.org). I use all types of forcing files: river runoff, wind forcing, tides, open ocean boundary conditions, etc. I want to port the entire project to CROCO and try out the non-hydrostatic solver on the same domain. Can I just use all the forcing files as they are? Any thoughts on which forcing files are compatible?

In principle, yes. It might not be trivial.

CROCO uses only one forcing file, where tide information is included, and only one boundary file. River runnof is added in an external file (croco_runoff.nc).

You might have problems in the variable names are different, but that is something that can be fixed using NCO tools.

Compare and post the output from

ncdump -h

for your ROMS_Rutgers and the files produced for the default Benguela case, to see if we can spot the differences.
