I noticed the description of SRC_APP_MAP in https://www.airqualitymodeling.org/index.php/CMAQv5.0.2_Integrated_Source_Apportionment . And I have downloaded CMAQv5.0.2 and Spatial Allocator v4.3 in github ,but I haven’t found the file src_app_map.tar.gz ,statefp_mask_all.* or alloc_create_areaperce…

Hi Bsu, First of all, you should have individual emission inventories that devided by categories,such as agritulture.nc,industry.nc,power.nc Then, you can change the line : setenv N_EMIS_GR 3 as there are 3 different emission inventories. And declare each emission inventories in run_cctm.csh.For…

The upcoming release of CMAQv5.3 beta that will include the option to build and run CCTM ISAM.

I agree with Liz that waiting for the next CMAQ release will get you a better ISAM code. But I think you are asking about how to create map file to allocate emissions by regions. Unfortunately, I don’t know of any tools to help you. This is something you need to come up on your own. For an examp…

Thanks for answering my question，but the description in CMAQv5.0.2 isam release notes says as follows： SRC_APP_MAP is an optional input to ISAM that defines emissions tagging source regions. The I/O API gridded map file can be created using the Spatial Allocator with an input shapefile to comput…

Hi， May I ask a question ，If I want to research PM2.5， which TAG CLASSES I need to track I have used CMAQ5.3.1 and I don’t know how to set the isam_control.txt： !!! CMAQ-ISAM tag definition control file !!! (lines begining with !!! - three exclamaition marks - are ignored by the text parser) …

Hi Bsu， As described in https://github.com/USEPA/CMAQ/blob/master/CCTM/src/MECHS/cb6r3_ae7_aq/SpecDef_cb6r3_ae7_aq.txt PM2.5 is calculated as: PM25_TOT=ATOTI[0]*PM25AT[3]+ATOTJ[0]*PM25AC[3]+ATOTK[0]*PM25CO[3] ATOTI=ASO4I[1]+ANO3I[1]+ANH4I[1]+ANAI[1]+ACLI[1] +AECI[1]+AOMI[0]+AOTHRI[1] ATOTJ=AS…

Thank you so much ~ Recently, I’ve learned how to tag different regions through the variable ‘REGION(S)’ in the ‘isam_control.txt’ and the variable ’ ISAM_REGIONS’ in the run_cctm.csh . May I ask a question about how to tag the contributions of different emission category? such as agriculture，in…

Hi,may I ask a question, I have used CB05 Emission inventory to run CMAQ5.3.1(CB06), What coefficients do I need to modify to make them match？ Thank you~

Please start a new issue for this question.
