Here is a configuration I used in CMAQv5.3.2 runscript to activate the WBDUST module:
setenv CTM_WB_DUST Y setenv CTM_WBDUST_BELD UNKNOWN setenv CTM_DUSTEM_DIAG Y if ( $CTM_WB_DUST == 'Y' ) then # Input variables for BELD3 Landuse option #setenv DUST_LU_1 $LUpath/beld3_12US1_459X299_output_a.ncf #setenv DUST_LU_2 $LUpath/beld4_12US1_459X299_output_tot.ncf endif
Above configuration (and also another run with setenv DUST_LU_1 and setenv DUST_LU_2 uncommented) resulted in the output CCTM_DUSTEMIS_* files having 0 emissions for any PM species (fine or coarse) at any timestamp, while the CCTM_CONC_* file has ASOIL concentration that is nonzero. The only ‘problem’ I see is this message on the CCTM_LOG_* file:
What could I have missed that would lead to CCTM_DUSTEMIS_* files having zero PM emission for all timestamps, while the CCTM_CONC_* file has nonzero ASOIL concentration?
