How to implement the same climate forcing in different compsets?

What version of the code are you using?

We use CESM 2.1.4, running on Derecho.





Describe every step you took leading up to the problem:

We want to explore the effects of land cover change-atmosphere interactions on ecosystem productivity/photosynthesis. We plan to run 4 simulations, the F2000climo component with 1984 land cover data, the F2000climo component with 2014 land cover data, the I2000Clm50Sp component with 1984 land cover data, and the I2000Clm50Sp component with 2014 land cover data. Apart from the land cover change part, we did not make any other changes.



Describe your problem or question:

We found that the initial data/climate forcings of the F2000climo and I2000Clm50Sp compsets are inconsistent. We would like to run the 4 simulations mentioned above with the same initial data/climate forcings. How do we implement this? Do we need a branch run? Which compsets are best to run it with? How long do we need to run it to spin up?
