There are no variables related to dust in the wrinput and wrfout files.

[XHY]

Dear friends, I encountered some issues when simulating "dust only". I checked the geo emd01 and met emd01 files, and found that they both contain parameters related to erod, sandfrac, and clayfract. However, when I ran the "real.exe" file, I couldn't find the variables related to dust. The same happened when running "wrf.exe". Could it be that there is a problem with my namelist.input? I hope you can help me out. Thank you all.
The relevant information is as follows:

[xiahy@mgt run]$ ncdump -h wrfinput_d01 | grep -E -i "dust|sand|aer|pm|dust_[0-9]|emiss_dust|depo_dust"
dust_erosion_dimension = 3 ;
float EROD(Time, dust_erosion_dimension, south_north, west_east) ;
:AERCU_OPT = 0 ;
:AERCU_FCT = 1.f ;
[xiahy@mgt run]$ ncdump -h wrfout_d01_2025-04-11_00:00:00 | grep -E -i "dust|sand|aer|pm|dust_[0-9]|emiss_dust|depo_dust"
:AERCU_OPT = 0 ;
:AERCU_FCT = 1.f ;
:AER_OPT = 0 ;
:AER_TYPE = 1 ;
:AER_AOD550_OPT = 1 ;
:AER_ANGEXP_OPT = 1 ;
:AER_SSA_OPT = 1 ;
:AER_ASY_OPT = 1 ;
:AER_AOD550_VAL = 0.12f ;
:AER_ANGEXP_VAL = 1.3f ;
:AER_SSA_VAL = 0.85f ;
:AER_ASY_VAL = 0.9f ;
