SST Perturbations

I am wondering if some one can help me to generate ensemble runs using CAM4. I run the model from 1980 to 2010 with prescribed SST and now I want to make 5 or 6 more runs of CAM4 with the same setting but with some perturbation. I know there is "pertim" option in CAM for the perturbation in initial conditions (ICs) but my control runs span around 20 years and therefore perturbation in the ICs are not useful for me. I want to perturbed SST or sea (boundary condition) to make ensemble runs I guess or any other way ? I have heard about AMIP runs of ensemble CAM4 but there is no information on Internet about how these ensemble members are generated.
