Dear WRF-Hydro Team,

I hope you are doing well.

I am trying to run WRF-Hydro in offline mode for a test case I recreated based on the Croton example. However, I am facing the following error when running the model:

NetCDF: Not a valid ID ***** READ_HRLDAS_HDRINFO: Problems finding dimension 'west_east'


I have double-checked my forcing files (LDASIN), domain files (geo_em.d01.nc and Fulldom_hires.nc), and namelists, and everything seems correct in terms of dimensions and structure. The LDASIN files include south_north, west_east, Time, and other expected variables. The geo grid also seems fine.

Despite this, the model crashes with this error.

I would appreciate your guidance on how to troubleshoot it.

Best regards,
Fatemeh

Hi Fatemeh,

Most of the time this error suggests one of the files in the namelists is not pointing to the right file or right path. Could you please double check the paths in the namelists?

Thanks!
Arezoo
