Hello everyone,
Normally I prefer to troubleshoot WPS or WRF on my own, however, I'm running out of ideas to resolve this issue. My procedure to run WRFv4.1.3 utilizing HRRR (form http://home.chpc.utah.edu/) is as follows:
1.a) Obtain HRRR data using Python via the following script <https://gist.github.com/blaylockbk/78d4dd9c159e8974f288b0a57f68c266?fbclid=IwAR31oIBBe9JcQPu7QKq-fIzp5r9skUSIiUMFLuBo_L8U7Y2zbe_kaXNT_tU>
1.b) Download 'prs' and 'sfc' data.
[Using WPSv4.0]
2) Run geogrid.exe [finishes successfully]
3) Run ungrib.exe using the following Vtable <https://github.com/blaylockbk/Ute-WRF-User-Group/blob/master/Blaylock/WPS_for_HRRR/Vtable.HRRR.bkb>. I noticed other, more recent Vtables (for HRRR) fail to extract 3-d variables (I'm running WRFv4.1.3 for 2017-10-28 so I believe the grib tables aren't for the appropriate date). I ran ungrib.exe for both 'prs' and 'sfc' data then combined their ungribed files into met_em*.nc files via metgrid.exe. I also ran ungrib.exe and metgrid.exe using only 'prs' data. Regardless, both processes lead to the same error during real.exe. [finishes successfully]
4) Run metgrid.exe using this METGRID.TBL <https://github.com/blaylockbk/Ute-WRF-User-Group/blob/master/Blaylock/WPS_for_HRRR/METGRID.TBL.HRRR.bkb>. I read in another thread that changing 'FLAG_SOIL_LEVELS' to '0' in METGRID.TBL worked for their simulation(s). I tried running real.exe using the original METGRID.TBL (unchanged) file along with its suggested alteration (FLAG_SOIL_LEVELS==0)... Again, both attempts led to the same error in real.exe. [finishes successfully]
WRFv4.1.3
5) Run real.exe... When I run real.exe without the following namelist.input options:
sfcp_to_sfcp = .true.,
sjust_height = .false.,
interp_type = 1,
lowest_lev_from_sfc = .false.,
force_sfc_vinterp = 1,
etc,
I receive this error: "not enough info for a p sfc computation"
Unfortunately, with the added namelist.input options listed above, I receive this error: "pal, linear is about as low as we go"
I tried different Vtables, METGRID.TBLs, and namelist.input options to solve this problem. Nothing is working at the moment. I haven't made it past this error (usually fails after 10-12 seconds).
I'd really appreciate any suggestions or help that anyone may provide!
I attached my namelist.input, metgrid.log, ungrib.log, METGRID.TBL, and GEOGRID.TBL file. At the moment, I cannot attach the Vtable or rsl.error.out files (I'll add them later if requested!).
Thanks!!!
