MOSAIC seems to have 1 bug in modal_aero_amicphys.F90

[xnnzka]

What happened?

Recently I have to use CAM-Chem and MOSAIC to simulate NH3 related chemicals. I follow https://wiki.ucar.edu/spaces/camchem/pages/562823413/Use+MOSAIC+scheme+in+CESM+CAM-chem to download MOSAIC source codes zz_cam6_3_018_mosaic0.3. But I meet an error in building case:
5635 | if ( mwaer_from_advmass ) then
| 1
Error: IF clause at (1) requires a scalar LOGICAL expression
I review the source codes in modal_aero_amicphys.F90 and find in line 93: integer, public :: mwaer_from_advmass = .false. .
I modify integer to logical and the case could build and run successfully.

What are the steps to reproduce the bug?

1. git clone https://github.com/ESCOMP/CAM -b zz_cam6_3_018_mosaic0.3 MOSAIC_CODE
2. rename CESM2.2.2/components/cam to CESM2.2.2/components/cam_origin and then copy mosaic_code to CESM2.2.2/components/ and rename cam
3. setup a FCHIST case and build
   (I knew that mosaic in FHIST compset will not work. Because FCnudged needs to download so much data from MERRA2 so I use FCHIST to test.)

What CAM tag were you using?

CAM in CESM2.2.2

What machine were you running CAM on?

Other (please explain below)

What compiler were you using?

GNU

Path to a case directory, if applicable

No response

Will you be addressing this bug yourself?

Yes

Extra info

I use the cluster of my university (https://qingli411.github.io/eesrf-hpc-user-guide/hpc1/environment.html).

I want to know if my modification is reasonable? Very looking forward to reply and thx!

And I also want to know if "rename CESM2.2.2/components/cam to CESM2.2.2/components/cam_origin and then copy mosaic_code to CESM2.2.2/components/ and rename cam" is correct? Even though https://wiki.ucar.edu/spaces/camchem/pages/562823413/Use+MOSAIC+scheme+in+CESM+CAM-chem introduces how to use MOSAIC, I am still confused which folder I should put the MOSAIC source codes in. At the beginning, I just put it in CESM2.2.2/components/mosaic, but when I build my case, I found there was an error: Command: '/CESM2.2.2/components/cam/bld/configure -s -fc_type gnu -dyn fv -hgrid 0.9x1.25 -cpl mct -usr_src /cesmrun/FCHIST_mosaic/SourceMods/src.cam -spmd -nosmp -ocn docn -phys cam6 -chem trop_strat_mam4_vbs -age_of_air_trcs -mosaic -usr_mech_infile /mosaic_code/MOSAIC_MECH_FILE/MZ272_TS1.1_simpleVBS_MOSAIC_20210528.in' failed with error 'Unknown option: mosaic'.
I am sorry that my question might be strange because I have never used chemistry mode in CESM. This time I needed to use CAM-Chem and MOSAIC because this is my final project for my course.
