Basic timing information from COSP2 in CESM2.

Hi COSP users,

Below you will find some basic timing information (provided by Jen Kay) for COSP2 in CESM2. These results are for a 1-month CMIP6 historical simulation with 3 configurations (no COSP, COSP w/o radar simulator, All COSP). Take home message, COSP2 doesn't require too many resources, ~5% increase, so you should implement it in your model!

CESM2 B1850 - no COSP - /gpfs/u/home/jenkay/fis/cesm2/cesm2p1_B1850optPE
