The path of the file
inputdata/atm/cam/solar/SolarForcing1995-2005avg_c160929.nc
and the values that you quoted
1361.1
suggest to me that this file contains the top-of-atmosphere solar radiation used by an active atmosphere model (CAM). If you do not use an active atmosphere model, then I suspect that this file and its values are ignored.
I do not have answers about volcanic forcing. I hope somebody else will answer.
