Remove dust_a1 ability to act as a CCN

[Paul F]

Hi all,

I am currently trying to remove the ability of dust_a1 to work as a cloud condensation nuclei (CCN) in CESM2.1.5. To be honest I am not sure as to where I should start with this. I already looked at some routines such as ndrop_bam.F90 but I do not have any experience with this part of the model.

I was wondering if anyone here already tried or succeeded in doing something similar.

Thanks in advance for the help,

Best,
Paul

Hi Paul, thanks for writing. I am not sure if this was previously achieved. From the tracer name you mentioned (dst_a1) this seems to be for the modal aerosols (MAM) so you would need to look in ndrop.F90 instead of ndrop_bam.F90 (which is for the bulk aerosol model BAM).

Hi Haipeng,

Thanks for the help, I'll have a look!
