Previously, primary PM2.5 emissions were split into 5 species: OC, EC, sulfate, nitrate, and PMFINE (unspeciated). We now split primary PM2.5 emissions into 18 species: OC, EC, sulfate, nitrate, H2O, Na+, Cl-, NH4+, non-carbon organic matter (NCOM), Al, Ca2+, Fe, Si, Ti, Mg2+, K+, Mn, and Other (note that PMFINE is now called PMOTHR). The speciation profiles are taken directly from Reff et al. (2009).
Four species were explicitly treated in previous versions of CMAQ but were not modeled as being emitted from anthropogenic sources: H2O, Na+, Cl-, and NH4+.
NCOM is needed to accurately model total organic mass.
Al, Ca2+, Fe, Si, and Ti are major crustal elements and are useful for evaluations against IMPROVE’s dust measurements.
Mg2+, K+, and Ca2+ are inputs for ISORROPIAv2.1.
Fe and Mn are catalysts for aqueous-phase SO2 oxidation. Model estimates of Fe and Mn concentrations now replace default values that were used in previous versions of CMAQ as described in the ISORROPIAv2.1 section of the release notes.
目前中国国内主流的清单来自清华的MEIC,但是这个只支持aero5.
要做到aero6以上的排放,只能进行分配。但国内好像没有适合的分配系数(如果您有,能否私信分享于我?)
下图是国外的分配方案。仅供参考
