CESM1.5 (mini-breck version)
This is the cesm1.5 discussed at the mini breck. The so called "28".
The control runs for the "28" simulations (pre-industrial control, 20th century, standalone simualtions) can be found at here,All the other cesm1.5 development simulations can be found at: CESM1.5 simulations ("mini Breck" simulations)
Instructions to reproduce the preindustrial control for 28 are below.

Compset and create_newcase command
In this tag, the B1850 compset uses:
- ATM: cam5.5 physics
- SEA ICE: prognostic cice5
- LAND ICE: cism1 land ice
- LAND: clm5.0 physics + clm5.0 bgc (cn and methane)
- RIVER MODEL: MOSART
- OCN: POP2 default+ BGC (CO2=diag)
An example of the create_newcase command is:
./create_newcase -case $yourcasename -compset B1850 -res f09_g16 -mach yellowstone -user_pes_setby allactive -project $project_number
