All,

I've been working to get the WRF-Solar options working in my versions of WRF, v4.2. First, thank you to the developers for the helpful WRF-Solar user guide online - I was able to get the GHI, DNI, and DIF special variables output with no problem, and the output looks reasonable.

My problem is the variables output by the solar_diagnostics namelist option (e.g., CLDFRAC2D, CBASEHT, CTOPHT, CLDIDX, and SZA). I'm interested in having those output on the model grid, so have the solar_diagnostics option turned on - but nothing is output. I checked the rsl.error.0000 file, and see that the solar diagnostic module is not even being called. What could I be doing wrong?

Below is the &physics section of my namelist. Points that might be of interest are that I am using Thompson aerosol aware microphysics with RRTMG radiation along with the aer_opt=3 option, so the aerosols, microphysics, and radiation should all be fully coupled (or at least that is my intention). I am also using swint_opt=2 so FARMS is called every timestep.

Thanks in advance for any help you can provide.

Please try the reference configuration of WRF-Solar and let us know if you see the diagnostic variables in the output:
https://ral.ucar.edu/projects/wrf-solar
 
In addition to trying the reference WRF-Solar configuration, could you please post your full namelist.input file here? Thanks.
 
Sure, I can try using the reference configuration (with my model grid setup, so I don't have to rerun WPS). I can't use the reference configuration for my run though - are there specific namelist settings that might conflict?
 
I cannot think of anyone. That is why I was suggesting to use the reference configuration. This is a well tested configuration and knowing if this configuration runs fine, or not, should help to isolate the issue.
 
I ran the model using the reference configuration, and still no go on the solar variables being output. The SOLAR_DIAG printout isn't showing up in the rsl.error.0000 file, so it looks like the config_flags%solar_diagnostics variable is being reset somewhere. Would welcome any advice.

Ran the model again outputting config_flags@solar_diagnostics right before its call in module_diagnostics_driver and can confirm it is being set to 0 at some point.
 
The correct name for the namelist block is diags. You are missing the letter s at the end. The correct setting is:
&diags
solar_diagnostics = 1,
