Question About EDGAR Mapping for chem_opt=204 in WRF-Chem

[Naser]

Hello,

I would like to run WRF-Chem using chem_opt=204 (SAPRC99 chemistry with MOSAIC using the KPP library).

I would like to prepare anthropogenic emissions using EDGAR data. However, I currently only have these two mapping files:

• MOZCART.inp
• MOZART-MOSAIC.inp

I would like to know whether SAPRC99 (chem_opt=204) uses the same mapping as MOZART-MOSAIC.inp, or if there is another specific mapping file for SAPRC99 chemistry.

If there is another appropriate mapping file or any related guidance, I would greatly appreciate it if you could share it with me.

Thank you very much.

Naser

Hi Naser, I don't know the content of the mapping files you mentioned but SAPRC99 uses emiss_opt = 13. Just make sure that you are mapping the chemical species listed for this emiss_opt. You can check the list under registry.chem, which is copied below:

package esaprcnov emiss_opt==13 - emis_ant:e_so2,e_c2h6,e_c3h8,e_c2h2,e_alk3,e_alk4,e_alk5,e_ethene,e_c3h6,e_ole1,e_ole2,e_aro1,e_aro2,e_hcho,e_ccho,e_rcho,e_acet,e_mek,e_isoprene,e_terp,e_sesq,e_co,e_no,e_no2,e_phen,e_cres,e_meoh,e_gly,e_mgly,e_bacl,e_isoprod,e_methacro,e_mvk,e_prod2,e_ch4,e_bald,e_hcooh,e_cco_oh,e_rco_oh,e_nh3,e_pm25i,e_pm25j,e_eci,e_ecj,e_orgi,e_orgj,e_so4i,e_so4j,e_no3i,e_no3j,e_orgi_a,e_orgj_a,e_orgi_bb,e_orgj_bb
