Apparent bug in generation of cam.input_data_list

I am attempting to build the F1850C5 compset, f09_g16 resolution on Yellowstone with chemistry turned off, using tag cesm1_2_beta04. When I set "-chem none" (using xmchange --append CAM_CONFIG_OPTS="-chem none") to turn chemistry off, the first line of the auto-generated Buildconf/cam.input_data_list looks like this:

tracer_cnst_file = /oxid_1.9x2.5_L26_1850clim_c091123.nc

This file (or, at least, a file with an identical name) is obviously not located at the root, and rather looks to be actually located here:

/glade/p/cesm/cseg/inputdata/atm/cam/chem/trop_mozart_aero/oxid

Is this a potential error on my part, or an issue with the auto-generation of the cam.input_data_list file? I note that when I include chemistry (i.e., by excluding "-chem none"), this is not an issue.

Thanks for the help (in advance).

Hi Jeremy,

Try adding

prescribed_aero_model='bulk'

To user_nl_cam in your case directory. Prescribed modal aerosols are not support yet, so you'll need to
use bulk aerosols.
