Add solar forcing to a B composet?

[leelay]

Hi everyone, I was trying to assimilate some artificial forcing to the simulation. I was wondering if it is reasonable to utilize solar forcing (or something else, aerosol, etc) in a B composet?
If it is OK to do so, what should I do? I have checked the post"Running CLM with ERA5 forcings".
So the sequence to do so is like this?
1. prepare solar radiation data in nc format.
2. modify variables in cam namelist(user_nl_cam)
3. setup & build & submit?

Thanks in advance!

For a B1850, the solar forcing in CAM is read in:
path_to_input_data/atm/cam/solar/SolarForcingCMIP6_18491230-22991231_c171031.nc
This gives you the template that CAM is expecting for the solar data.

You can do
./case.setup
./case.buiid using that file.

If you create your own solar forcing, say in a file:
path_to_your_solar_data/atm/cam/solar/your_solar_data.nc

You need to add the line in user_nl_cam:
solar_irrad_data_file = 'path_to_your_solar_data/atm/cam/solar/your_solar_data.nc'

Then you can do
./preview_namelists
./case.submit.

Thank you so much! Having read your tutorial PDF and this reply, quite useful!
