model and IMPROVE observations for OC aerosol concentrations in the US[Park et al., 2003]</p></li><li><p>GAS-PHASE CARBON MASS CLOSURE?2847 organic compounds identified in the atmosphere [Graedel et al., 1986]~104 compounds estimated to be present [Goldstein and Galbally, 2006]30-100 compounds quantified in typical measurement campaigns[Roberts et al., 1998]Chebogue Pt, 1993 (NARE)C2-C7 agree with total measured within measurement uncertaintyT/S ~ 1+UCLA, 1999-2000WINTERSUMMERT/S ~ 1+T/S =1.4-2.2Suggest that 20-45% NMOC unmeasured in photochemically aged airmasses [Chung et al., 2003]</p></li><li><p>PHASES OF ORGANIC CARBON GENERALLY CONSIDERED SEPARATELY OR ONE-WAYOxidation &amp;CondensationPOASOADepositionDepositionOxidation toCO/CO2</p></li><li><p>CONSIDER TOTAL ORGANIC CARBON (TOC)Oxidation &amp;CondensationDepositionOxidation toCO/CO2Oxidation &amp;Re-volatizationTOCNote:Similar to defining nitrogen family (NOy)SEMI-VOLATILESCH4 Oxidation</p></li><li><p>FIELD SITES AND CAMPAIGNSEleven datasets upwind/over/downwind of North America with simultaneous observations of gas phase and particle phase OC.(Over 130 organic compounds measured)TOC = gas-phase OC + aerosol-phase OCTOOC = Total Observed Organic Carbon [gCm-3 @ STP]</p></li><li><p>MEAN DAYTIME TOOC OVER NORTH AMERICAIncreasing ageMean TOOC ranges from 4.0 gCm-3 (Trinidad Head, cleanest) to 456 gCm-3 (Mexico City, polluted) and generally decreases with age.Aerosol makes up 3-17% of TOOC.</p><p>ALL</p><p>ORGANIC BUDGET NORTH AMERICA</p><p>SITETypeRangeAir
