coupling WRF_CROCO

edit

Coupling is very sensitive to netcdf libraries. I think that your nco is overwriting the paths to the original netcdf librarry you used to compile the models, and that's why you have an error. You need nco for preprocessing, but then you need to unload the nco module, and come back to the original netcdf library you used to compile when you want to run.

The toolbox is set up of that, but to use this functionality, you need to define your nco module in an environment variable named 'ncomod' in the myenv_mypath.sh file :

export ncomod='your_nco_module'

Then, the scripts are prepared to load this module when needed, and unload it after, to avoid any conflicts with the netcdf library that you need for running (same than that you compiled with).

So basically, you should have at the beginning of myenv_mypath.sh something that looks like this example (with your own modules):

!/bin/bash

This kind of error messages

ncwa: command not found

indicate that you haven't installed the NCO package.

Please install it. In Ubuntu this is done with

sudo apt-get update sudo apt-get install nco

and try again.
