We use biogenic volatile organic chemical (VOC) emissions generated by the MEGAN model , including the individual VOC components that are considered secondary organic aerosol (SOA) precursors by GEOS-Chem. We use mineral dust emissions generated by the "DustDead" GEOS-Chem algorithm . The DustDead model simulates emissions of mineral dust that are mobilized by wind (excluding road dust). The "EMIS_DST1" and "EMIS_DST2" variables were used in this study to represent primary PM2.5 emissions. We use soil NOx emissions from the GEOS-Chem soil NOx extension . These emissions are at 0.25×0.3125 degree spatial resolution and for year 2016, downloaded from the GEOS-Chem FTP website (GEOS-Chem authors, 2019).
