Dear all,
I have a small query regarding the computation of the perturbation in atmospheric variables due to aerosol-cloud interaction (ACI) using the WRF-Chem model. In the case of aerosol-radiation interaction (ARI), the perturbation in atmospheric parameters can be computed by taking the difference between two experiments: (a) ARI on and (b) ARI off. So, is it the same for ACI, too (i.e., by taking the difference between two experiments: (a) ACI on and (b) ACI off)?
For your information, I gave ACI simulation by setting the following namelist:
progn=1
chem_opt=11
aer_ra_feedback = 0
aer_op_opt = 0
opt_pars_out = 0
cldchem_onoff = 1
wetscav_onoff = 1
conv_tr_wetscav = 1,
conv_tr_aqchem = 1,
Note that ARI is switched off to separate ACI from ARI.
Now, if I have to give a simulation, considering without ACI, then should I set up the namelist like in the following:
progn=1
chem_opt=11
aer_ra_feedback = 0
aer_op_opt = 0
opt_pars_out = 0
cldchem_onoff = 0
wetscav_onoff = 0
conv_tr_wetscav = 0,
conv_tr_aqchem = 0,?
Is this approach correct? Can anyone please guide me on this? That will be highly appreciated. Thank you for your time and consideration.
With regards,
Ankan
