“…Deposition velocities of ∼0.17-0.36 cm s −1 have been reported for the ocean (Mao et al, 2006;Warneke and de Gouw, 2001). Since acetone is both emitted from oceans and deposited to them, it has been suggested that oceans act as a reservoir for acetone, i.e., a sink for polluted air masses and a source for relatively clean air masses de Reus et al, 2003;Williams et al, 2004). In rural areas biogenic emissions of acetone have been reported to be substantial, e.g., 23% of total C emissions from a pasture of grass and clover in Australia (Kirstine et al, 1998).…”

Abstract.A long-term, high time-resolution volatile organic compound (VOC) data set from a ground site that experiences urban, rural, and marine influences in the Northeastern United States is presented. A proton-transfer-reaction mass spectrometer (PTR-MS) was used to quantify 15 VOCs: a marine tracer dimethyl sulfide (DMS), a biomass burning tracer acetonitrile, biogenic compounds (monoterpenes, isoprene), oxygenated VOCs (OVOCs: methyl vinyl ketone (MVK) plus methacrolein (MACR), methanol, acetone, methyl ethyl ketone (MEK), acetaldehyde, and acetic acid), and aromatic compounds (benzene, toluene, C 8 and C 9 aromatics). Time series, overall and seasonal medians, with 10th and 90th percentiles, seasonal mean diurnal profiles, and inter-annual comparisons of mean summer and winter diurnal profiles are shown. Methanol and acetone exhibit the highest overall median mixing ratios 1.44 and 1.02 ppbv, respectively. Comparing the mean diurnal profiles of less well understood compounds (e.g., MEK) with better known compounds (e.g., isoprene, monoterpenes, and MVK + MACR) that undergo various controls on their atmospheric mixing ratios provides insight into possible sources of the lesser known compounds. The constant diurnal value of ∼0.7 for the toluene:benzene ratio in winter, may possibly indicate the influence of wood-based heating systems in this region. Methanol exhibits an initial early morning release in summer unlike any other OVOC (or isoprene) and a dramatic late afternoon mixing ratio increase in spring. Although several of the OVOCs appear to have biogenic sources, differences in features observed between isoprene, methanol, acetone, acetaldehyde, and MEK suggest they are produced or emitted in unique ways.

“…We take mean VOC decay lifetimes to formaldehyde from empirical satellite formaldehyde column observations: seven hours for isoprene and five hours for monoterpenes . We also use a decay lifetime to formaldehyde for acetone of 15 days (Singh et al, 2004;de Reus et al, 2003). These lifetimes scale inversely with diurnal fluctuations in OH from Martinez et al (2003).…”

Sources of carbon monoxide and formaldehyde in North America determined from high-resolution atmospheric data

et al. 2008

Abstract. We analyze the North American budget for carbon monoxide using data for CO and formaldehyde concentrations from tall towers and aircraft in a model-data assimilation framework. The Stochastic Time-Inverted Lagrangian Transport model for CO (STILT-CO) determines local to regional-scale CO contributions associated with production from fossil fuel combustion, biomass burning, and oxidation of volatile organic compounds (VOCs) using an ensemble of Lagrangian particles driven by high resolution assimilated meteorology. In many cases, the model demonstrates high fidelity simulations of hourly surface data from tall towers and point measurements from aircraft, with somewhat less satisfactory performance in coastal regions and when CO from large biomass fires in Alaska and the Yukon Territory influence the continental US.Inversions of STILT-CO simulations for CO and formaldehyde show that current inventories of CO emissions from fossil fuel combustion are significantly too high, by almost a factor of three in summer and a factor two in early spring, consistent with recent analyses of data from the INTEX-A aircraft program. Formaldehyde data help to show that sources of CO from oxidation of CH 4 and other VOCs represent the dominant sources of CO over North America in summer.

“…Other terrestrial sources include biomass burning (Simpson et al, 2011) and direct anthropogenic emissions (Goldan et al, 1995;Goldstein and Schade, 2000;de Gouw et al, 2005). Globally, the oceans appear to be both a gross source and a gross sink for atmospheric acetone (Fischer et al, 2012); however, the magnitude and variability of the corresponding net flux is quite uncertain (de Reus et al, 2003;Williams et al, 2004;Lewis et al, 2005;Marandino et al, 2005;Sinha et al, 2007;Taddei et al, 2009;Fischer et al, 2012;Read et al, 2012;Sjostedt et al, 2012). Along with gross oceanic uptake, sinks of atmospheric acetone include photochemical oxidation by OH, photolysis, and deposition to land (Chatfield et al, 1987;McKeen et al, 1997;Gierczak et al, 1998;Blitz et al, 2004;Karl et al, 2010).…”

We apply a full year of continuous atmospheric acetone measurements from the University of Minnesota tall tower Trace Gas Observatory (KCMP tall tower; 244 m a.g.l.), with a 0.5° × 0.667° GEOS-Chem nested grid simulation to develop quantitative new constraints on seasonal acetone sources over North America. Biogenic acetone emissions in the model are computed based on the MEGANv2.1 inventory. An inverse analysis of the tall tower observations implies a 37% underestimate of emissions from broadleaf trees, shrubs, and herbaceous plants, and an offsetting 40% overestimate of emissions from needleleaf trees plus secondary production from biogenic precursors. The overall result is a small (16%) model underestimate of the total primary + secondary biogenic acetone source in North America. Our analysis shows that North American primary + secondary anthropogenic acetone sources in the model (based on the EPA NEI 2005 inventory) are accurate to within approximately 20%. An optimized GEOS-Chem simulation incorporating the above findings captures 70% of the variance (R = 0.83) in the hourly measurements at the KCMP tall tower, with minimal bias. The resulting North American acetone source is 11 Tg a⁻¹, including both primary emissions (5.5 Tg a⁻¹) and secondary production (5.5 Tg a⁻¹), and with roughly equal contributions from anthropogenic and biogenic sources. The North American acetone source alone is nearly as large as the total continental volatile organic compound (VOC) source from fossil fuel combustion. Using our optimized source estimates as a baseline, we evaluate the sensitivity of atmospheric acetone and peroxyacetyl nitrate (PAN) to shifts in natural and anthropogenic acetone sources over North America. Increased biogenic acetone emissions due to surface warming are likely to provide a significant offset to any future decrease in anthropogenic acetone emissions, particularly during summer
