Problem with nudging options

Hi everyone,
I am planning to run a seasonal simulation using ERA5 reanalysis data. For the long-term run, I intend to use spectral nudging. Up to the real.exe stage, everything works fine. However, when running wrf.exe, the model stops at the initial time step. The namelist.input and error files are available in the "Nudging" folder at the link provided below.

To check if the issue is related to my initial data, I commented out the nudging options while keeping all other settings the same. With nudging disabled, the model runs without any errors. This indicates that the problem is likely related to the nudging configuration. The corresponding namelist and rsl.out file for the successful (non-nudged) run are available in the "CTL" folder.

Based on the current error message, I’m unable to determine the exact cause or how to resolve it. I would appreciate any suggestions or guidance to help overcome this issue.

Thank you. The issue was due to some missing input options in the namelist.input file. I have corrected it, and the model has now started integration successfully.
I want to apply nudging, but not within the PBL. Could you please review the namelist.input file and confirm whether the nudging options are set correctly?


Thank you,
Sree
 
Hi,
From what I can tell, I believe you have it set up correctly. I'm glad you were able to solve your original issue, and thanks for the update!
