Error while running real.exe. "Could not find trapping x locations"

[Vaishnavi_198]

Hello,

I am trying to run a WRF model using IC/BC from CMIP6 CESM-WACCM data on WRF v3.9. I made WPS intermediate files using a python library called 'Pywinter'. I was able to successfully run metgrid.exe with it. But when I try to run real.exe. I get the following error..
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I have attached namelist.wps, intermediate file, namelist.input, met_em file, rsl error file in nextcloud. The zip file is called 'int.zip' (Forum Uploads).

Thank you

Hi,
When you downloaded the CMIP6 data, did you make sure to download a global set of the data, and not just a subset? Did you also make sure to obtain all the surface fields mandatory?

Since you're using an older version of WRF, just to rule out a version issue, can you also try this with the latest wrf code (V4.6.0)? Thanks!

Hi Kelly,

The data is global data and my files contain all mandatory fields. It turns out the input CMIP6 NETCDF files did not have data over land for U,V,T 3D parameters, they were all NaN values, I was not aware of this. I think this must be causing the error when real tries to interpolate vertically.

I plotted the input NetCdf file for wind velocity to check if something was wrong with the input, as shown it does not have values over land.



I'll use a different CMIP6 model and see if I am able to run the model.

Thank you so much
