Sensitivity of summertime surface ozone to surface temperature over Southeastern U.S.: Interannual variability as a diagnostic for chemical transport models Tzung-May Fu (tmfu@pku.edu.cn) Dept. of Atmospheric & Oceanic Sciences, Peking University Yale + NUIST video conference April 19, 2013

3 Role of atmospheric chemistry in the Earth system International Global Atmosphere Chemistry (2006) Science Plan and Implementation Strategy : 通过整合对大气过程及地球系统响应与反 馈的理解, 增进对未来数十年大气化学组分 的预测能力 IPCC 4 th Assessment (2007) : 要准确预测未来气候变化, 模式必须正确考虑气候与其他决定大气温室气体 高活性气体及气溶胶浓度过程的反馈作用 3
4 Non-methane Volatile Organic Compounds(NMVOCs) Precursor to tropospheric pollutants O 3 Secondary Organic Aerosol(SOA) Chemical processes Anthropogenic + Biomass burning VOCs ~150 Tg y -1? Biogenic VOCs 500~1200 Tg y -1? Isoprene 280 ~ 850 Tg y -1? Ocean VOCs ~20 Tg y -1? Land Ocean
5 I. Satellite observational constraints on VOC emissions VOCs oxidize HCHO ( 甲醛 ) Top-down constraints on VOC emissions [Fu et al., 2007] Satellites observe: trace gases(o 3, NO 2, HCHO, CHOCHO, CO, SO 2, ) aerosols GHG(CO 2,CH 4 ) meteorology & climate variables land surface

7 Current knowledge of VOC emissions in Asia NOT consistent with observations State-of-the-art bottom-up reactive VOC emission inventories GEOS-Chem Anthropogenic 40 Tg Streets et al. [2003] Biomass burning 12 Tg Streets et al. [2003] Biogenic 80 Tg Guenther et al. [2006] Global chemical transport model Assimilated meteorology Resolution: 2.5 longitude x 2 latitude GOME HCHO column June 1996~2001 Model HCHO column June 2001 [10 16 molec cm -2 ] Fu et al. [2007]
8 GOME HCHO Monthly Columns over Asia ( ) Fu et al. [2007] Relationship to VOC emissions far more complex than for N. America; biomass burning, isoprene, anthropogenic VOCs, direct HCHO emission all contribute

10 Excess winter GOME HCHO due to Chinese vehicle emissions GOME 25% higher than model 1:1 Inventory by Streets et al. [2003] Observation by Barletta et al. [2005] Sampled 43 Chinese cities in Jan and Feb 2001 Inventory underestimates pentane & xylenes Underestimates vehicular emissions Fu et al. [2007]
11 HCHO column [10 16 molec/cm2] HCHO seasonal variation dominated by biogenic and biomass burning emissions GOME GEOS-Chem Model bkgd Biogenic Biomass x 2 Anthropogenic x 2 Fu et al. [2007] Bottom-up inventories capture the timing but not the magnitude of emissions
