WRF-Chem simulated aerosol feed back

Post by gc13141112 » Thu Apr 11, 2019 3:35 am

setting namelist.input for no aerosol feed back
progn = 0
ra_lw_physics = 4
ra_sw_physics = 4
chem_opt = 2
aer_ra_feedback = 0

setting namelist.input for aerosol direct effects
progn = 0
ra_lw_physics = 4
ra_sw_physics = 4
chem_opt = 2
aer_ra_feedback = 1

setting namelist.input for aerosol direct and indirect effects
progn = 1
ra_lw_physics = 4
ra_sw_physics = 4
chem_opt = 2
wetscav_onoff = 1,
cldchem_onoff = 1,
aer_ra_feedback = 1

I want to know actually how does progn = 1 works?
progn = 1 works for Morrison microphysics(mp option 40) but not for TE 2014 scheme(mp option 28) though TE 2014 scheme include the both direct and indreact effects.
Please explain. I have to clarify it.
