Guidance Needed: Configuring MAM7 for Aqua Planet Simulation Without Certain

Dear CESM Community,

I am currently working on an aquaplanet simulation using CESM, and I would like to disable specific land-based aerosol modes while using MAM7. The aerosol modes I want to remove are as follows:

  • Primary carbon
  • Fine dust
  • Coarse dust
However, I still want to keep sea salt aerosols active.

I have tried modifying the user_nl_cam file by adjusting the &chem_inparm, mode_defs, and rad_climate settings within the atm_in file, but I encountered errors during runtime.

Could you please help me with the following:

  1. How should I configure the relevant aerosol modes and parameters in user_nl_cam to disable these specific aerosol types?
  2. Are there any additional dependencies or specific configurations in the mode_defs or rad_climate sections that I need to address?
  3. Are there any examples or documentation available that explain how to disable these particular aerosol modes in MAM7?
Your help would be greatly appreciated.
