The namelist files or "in" files are useful to examine so you can see some of your options. The drv_in file is simple enough:

&ccsm_pes                                                                   
/                                                                           
&seq_infodata_inparm                                                        
 atm_adiabatic          = .true.                       makes atmosphere adiabatic only                             
 case_name              = 'barowave1deg'                                    
 ocean_tight_coupling           = .true.           not used here actually                        
 orb_iyear_ad           = 1990                        not used here either                     
 start_type             = 'startup'                       tells model to start from ICs file, rather than
                                                                    end of another run or 'restart'
/                                                                           
&seq_timemgr_inparm                                                         
 atm_cpl_dt             = 1800                          time step in seconds    
 restart_option         = 'monthly'                    frequency to write restarts (for purpose of
                                                                     stopping a run and restarting later, see start_type)                    
 start_ymd              = 101                             date of start, Jan 1, probably not used  here
 stop_n         = 30                                         length of run in days               
 stop_option            = 'ndays'                       units of stop_n                    
/                                                                           
&prof_inparm                                                                
 profile_single_file            = .true.                 I'm unsure what this is                   
/                                                                           
&pio_inparm                                                                 
/                                                                           

The atm_in field is horrible messy. It is mostly stuff not ready for this special case of adiabatic physics. I cannot figure out how to make the build script pare down the atm_in file to just the essentials. The following is one that I edited and it gave exactly the same output as the one in your directory. This tells you what is essential.

&phys_ctl_nl                                                                
 atm_dep_flux           = .false.                                Turns off aerosols                               
 cam_chempkg            = 'none'                              Turns of chemistry              
 cam_physpkg            = 'adiabatic'                         Makes atmosphere adiabatic              
 srf_flux_avg           = 0                                           not sure
/                                                                           
&gw_drag_nl                                                                 
 fcrit2         = 1.0                                                     a parameter we will talk about later  
/

                                                                               for adiabatic condition

 del2coef               =  3.e+5                                     damps velocity a bit       
 div24del2flag          =      2                                     a flag about velocity damping
 dtime          = 1800                                                 time step in seconds
 empty_htapes           = .true.                                  tells model not to output entire default set
                                                                                of variables which is ~100
 fft_flt                = 1                                                  controls amount of filtering at poles

'UU:I', 'V:I', 'VU:I', 'VV:I', 'Z3:I', 'Z500:I'                    these are the variables we do want sent                                                                                         to the output file. :I = instantaneous as
                                                                                opposed to :A = average over interval
 mfilt          = 31                                                       # of points in time per output file

 nhtfrq         = -24                                                    Interval between points in time outputted,
                                                                               the negative sign means units are hours,
                                                                               positive numbers are per time step
