1: Set up a BGC case#

We will create two different cases and compare the case directories. We want to check if the differences make sense. You will NOT run the model in this challenge exercise.

Exercise: Set up a BGC control case

Create a case called b_1850 using the compset B1850 at f19_g17 resolution.

Create a case called b_1850_bprp using the compset B1850_BPRP at f19_g17 resolution.

  • What happens when you run create_newcase? Follow the instructions to get this working, but don’t do it for real unless you know what you’re doing.

Run case.setup and preview_namelists for each case.

  • What changes occur when the carbon cycle is made prognostic?

POP BGC Specific Output#

ocn/hist/$CASE.pop.h.ecosys.nday1.????-??-??.nc

  • selected ocean ecosys variables at daily resolution

  • surface flux related, productivity, and functional group vertical integrals.

ocn/hist/$CASE.pop.h.ecosys.nyear1.????.nc

  • selected three dimensional ocean ecosys tracer budget terms.
