Custom SST and SIC boundary conditions for CAM6

Hi,
I am trying to create my own SST and SIC boundary conditions file to run CAM6 simulations. Specifically, I want to take the SST and SIC from CESM2 abrupt4xCO2 simulations and was planning on leaving atmospheric constituents at preindustrial levels. To start, I am comparing the TS and ICEFRAC variables from abrupt4xCO2 to SST_cpl and ice_cov from an existing boundary condition file, and I have a few questions.

1) The reference boundary condition file and model output have very different values over land. Do these affect the results, and if so, where do these values come from?

2) The reference boundary condition file has "prediddle" versions of SST and SIC. I'm trying to figure out whether I need to do this diddling. What is the purpose and does it affect the results?

3) Other than converting to Celsius, is there anything else I might need to do to convert TS and ICEFRAC to CAM6 boundary conditions?

Thanks in advance!
Margaret
