Holding the hygroscopic growth of aerosols invariant in PORT

[liren]

Dear all,

I am tring to use the CAM parallel offline radiation tool (PORT) to computing radiative forcing. In my experiment I have to perturb the temperature while holding the hygroscopic growth of aerosols is not affected by the modified temperatures and water vapor concentrations. I am not sure where I can find the proper steps I need to follow.

Thank you!

Have you looked at the documentation about PORT in the CAM6.3 User's Guide?

4. Atmospheric configurations (compsets) — camdoc documentation

ncar.github.io

If you have further questions, I am moving this to the CAM-Chem forum as they support PORT.

I read the user's guide again and found chapter 9. Physics modifications via the namelist may be useful. I will try it later. Thanks for your reply!
