Hi,
I have some confusion regarding the convective transport by the schemes. Do Grell-Freitas scheme support convective transport of chem species in WRF-Chem?
There is a pull request for implementation of GF scheme: https://github.com/wrf-model/WRF/pull/1121
However if you see this part of code from chem_driver.F
if( config_flags%cu_physics>0 .and. config_flags%chem_conv_tr>0 &
.and. config_flags%cu_physics/=kfcupscheme ) then
call wrf_debug(15,'calling conv transport for chemical species')
if(config_flags%chem_opt >0 )then
DO nv=PARAM_FIRST_SCALAR,num_chem_ct
chem_old(its:ite,kts:kte,jts:jte,nv) = chem(its:ite,kts:kte,jts:jte,chem_ct_indices(nv))
ENDDO
call grelldrvct(grid%DT,ktau,grid%DX, &
rho,grid%RAINCV_B,chem,
- - - - - - - - - - - - - - - - - --
chem_conv_tr=1 supported by Grell-freitas scheme, calls the grelldrvct from module_ctrans_grell.F which is for convective transport, wet deposition,etc.
Hence there is a conflict in my understanding whether GF scheme is implemented for convective transport,aqueous chem or not, as the pull request for its implementation and the code seem to be contradictory. It would be helpful if someone could clarify a bit. Appreciate your help & time.
