solar_diagnostics output variables not showing in WRFout

[julliana freire]

I've tried running WRF-SOLAR version 4.3 on a short simulation test to get the variables GHI, DNI, and DIF. But, none of them are shown in the wrfout file.

Following another topic in the forum (https://forum.mmm.ucar.edu/phpBB3/viewtopic.php?f=104&t=10331)
I used the reference configuration of WRF-Solar(https://ral.ucar.edu/solutions/products/wrf-solar) but again without any of the variables being output.

Thanks in advance for any help you can provide.

GHI should be in the output. It is a variable called SWDOWN.
The direct normal irradiance (DNI) and the diffuse irradiance are exposed via the Registry. You need to edit the file Registry.EM_COMMON and add the variables SWDDNI and SWDDIF to the WRF output by adding a h in the IO part of the table for these variables.

Thanks! It worked well.

Also, there is another option without recompiling.
1. Edit the namelist.input file, the &time_control namelist record
iofields_filename = "myoutfields.txt”
ignore_iofields_warning = .true.
2. prepare a text file ("my_output.txt") to select io fields:
+:h:0:SWDOWN,SWDDNI,SWDDIR,SWDDIF

Both options worked for my case.

Thanks!
