How to appropriately calculate radiative forcing imbalance

When running simulations with volcanic forcing in a fixed sea-surface temperature condition to get an estimate of the forcing, what output variables are the appropriate ones to use?

From what I understand, the standard way to do this is to calculate it as the sum of the shortwave + longwave top-of-atmosphere energy imbalance.

When looking at the table of output variables (Output Variables | Community Earth System Model) I find
FLNTtime: meanNet longwave flux at top of model
but no corresponding "Net shortwave flux at top of model", which I assumed would be the correct one to use when estimating radiative forcing.

Am I overlooking a output variable or is there some other suggested way of calculating radiative forcing within CESM?

And here's a graphic of CAM radiative fluxes.
