Some conerns about WRF4.2.1 and WRF solar

[snefe]

Hello,

I'm newbie to WRF and WRF solar. I'm asking you to help me clarify some concerns. Here are my questions :
1 - Is WRF solar V1 included in WRF 4.2.1 as stated in: "The WRF version 4.2 includes the enhancements of WRF-Solar Version 1 with upgrades in the physical parameterizations as well as other developments. Users are encouraged to use version 4.2.2 or upcoming versions." Or should I use version 4.2.2?
2 - I tried running WRF 4.2.1 without adding the "solar_diagnostic=1" part to the namelist.input, and I still got different irradiance types as SWDDIR, SWDDIRC, SWDDNI, SWDDNIC, SWDDIF in the output files. Is this normal?
3- I would like to work on the DNI and GHI. Are they SWDDNI and SWDOWN?
4- Is WRF solar V2 included in a specific version of WRF, like WRF solar V1?

Thank you in advance for your help.

It is always better to use newer version, ---- hence WRFv4.2.2 should be used in this case.

2 - I tried running WRF 4.2.1 without adding the "solar_diagnostic=1" part to the namelist.input, and I still got different irradiance types as SWDDIR, SWDDIRC, SWDDNI, SWDDNIC, SWDDIF in the output files. Is this normal?

These are state variables and they are included in wrfout, no matter whether you turn on solar_diagnostic or not

3- I would like to work on the DNI and GHI. Are they SWDDNI and SWDOWN?

These are variables specific for WRF-Solar. I am not sure ....

4- Is WRF solar V2 included in a specific version of WRF, like WRF solar V1?

I don't think WRF solar v1 includes v2. Instead, v2 is upgraded version of v1.

Thank you in advance for your help.
