Hello, everyone, I am planning to run some cases to simulate the stratospheric aerosol injection (for example, Injecting SO2 into the stratospheric) using CESM 1.2.2. I'm trying to run CESM1.2.2(WACCM5) now, and have established the corresponding case (compset:B1850W5CN res:f19_g16), but I don't know how to add the forced data. After watching some posts in the discussion forum, I learned that, CAM5 can use prescribed_volcearo_nl to add and adjust volcanic compulsion, however, I still don't know how to add volcanic forcing in WACCM5(CESM1.2.2).If anyone knows, can you tell me in detail? It's very important to me. Thank you very much.
