tracer_opt in the registry

As of 0a634ac
in Registry/registry.chem:

# tracer options. (smoke) only has one tracer for smoke (has to run with biomassburning).
#                 (test1) has lateral boundary tracer(1,2), stratospheric tracer(5,6),
#                     boundary layer tracer(7,8), surface tracer (3,4)
#                 (test2) has surface tracer replaced by smoke tracer

ifire=2 - the original WRF-Fire modified at NCAR

ifire=2 is using tracer_opt=3 only:

module_fr_fire_driver.F:346:     if(fire_ifun.eq.6 .AND. config_flags%tracer_opt.eq.3)then
module_fr_fire_driver.F:347:       call add_fire_tracer_emissions(config_flags%tracer_opt,grid%dt,grid%dx,grid%dy, &

in subroutine add_fire_tracer_emissions as

avgw = 1.0/(ir*jr)
...
emis=avgw*fire_tracer_smoke*burnt_area_dt(i_f,j_f)*fgip(i_f,j_f)*1000/(rho(i,kts,j)*dz8w(i,kts,j)) ! g_smoke/kg_air
tracer(i,kts,j,p_fire_smoke)=tracer(i,kts,j,p_fire_smoke)+emis

where in module_fr_fire_phys.F

real,pointer,dimension(:,:):: fgip                 ! init mass of surface fuel (kg/m^2)

and fire_tracer_smoke is namelist.input flag defined in registry.fire:

rconfig  real fire_tracer_smoke         namelist,fire         max_domains            0.02       -     "parts per unit of burned fuel becoming smoke (tracer_opt=3)" "g_smoke/kg_air"

ifire=1 - the original WRF-Fire continued as WRF-SFIRE

WRF-SFIRE is using tracer_opt=2 and sets all 8 tracers to the same value, but the postprocessing in wrfxpy uses only tr17_1. There is also tracer_opt=1 in the registry, which generates only one tracer smoke, but only if compiled with CHEM.

can i design the PM as a tracer?
