Segmentation fault in ungrib.exe with GDAS-FNL 0.25°

Hi everyone,

Using GDAS-FNL 0.25° with WPS 4.6.0. ungrib.exe worked with Vtable.GFS but stopped early. Tried Vtable.GFSPARA (through online), but now getting:
forrtl: severe (174): SIGSEGV, segmentation fault occurred
Has anyone got Vtable.GFSPARA working, or can share any Vtable that works?

Hi Stefan,

Could you please share the NCL script, as I'm trying to downscale CMIP6 data? It would be really helpful.

Many thanks.

I just want to add few things in the "Full WRF and WPS Installation Example (GNU)" > Install HDF5 > cd hdf5-1.10.5 : the unziped file name is different.

Hi Dear Ming,
I have WRF v4.5, and Prep-chem-src 1.5. I have generated met_em files. I have used Prep-Chem-Src for making emissions files. I can link those emission files with the wrf directory but I am stuck when it comes for multiple days in real.exe and wrf.exe runs.
What is the standard procedure for doing this?
Please help me in this regard.

Hi Dr. Chen,
I am using the WRF-Solar version 4.5. After some adjustments, I managed to run the simulation successfully with a single-layer grid. When I tried running it again with a three-layer nested grid, it still failed. Is the simulation failure related to the number of grid cells set for the simulation domain? I would like to understand the reason behind this.
Thank you.
