compset differences

[chillwx@gmail_com]

I am looking through the user's guide for CESM 1 and I cannot understand the difference between the compsets F_2000 and F_2000_CAM5. It states the F_2000_CAM5 uses cam5 physics, so what does F_2000 use?

F_2000 uses CAM4 physics.
You can find documentation about CAM4 and CAM5 physics at:
