How to calculate/output OLR at TOA of CAM5?

I am using the cesm-1.2.2 cam5 model, and I want to diagnose the outgoing longwave radiation (OLR) at top of atmosphere (TOA) rather than at top of model (TOM), but I didn't find the OLR in the output field namelist of CAM5. I just find FLNT ( Net longwave flux at top of model) and FLUT (Upwelling longwave flux at top of model). Do I have to modify the RRTMG radiation source code to add OLR output field or I can calculate OLR from the output fields. Thanks a lot!
