“…Composition of emission, model, and extract estimates Table 4 shows relative amounts of monoterpenes, oxygenated monoterpenes, and sesquiterpenes, measured with the REA, P. taeda branch enclosure estimates from Geron and Arnts (2010, G10); Helmig et al (2006, H06); Ortega et al (2008, O08) MEGAN emission estimates, and proportions from needle oil extracts (Daly and Geron, in preparation). There appears to be reasonable agreement in α-pinene composition between the REA data, enclosure data, MEGAN, and the review of Geron et al (2000a). Percentages ranged from 38 to 58%, while extracts were composed of 80% α-pinene.…”

“…Relative emission potential (REP) discussed in Geron et al (1994Geron et al ( , 2000a provides a means of ranking the importance of each tree species in the USDA FIA inventory as a BVOC emitter. REP is calculated as the product of the basal BVOC EF (for instance, total monoterpene in μg C g (leaf dry weight) −1 h −1 ), the estimated fraction of the total crown coverage within the US, and foliar density for each species.…”

“…Farnesene de novo synthesis induced by thermal or contact disturbance could possibly explain farnesene emission within branch enclosures, while farnesene is apparently absent in the needle extract and REA flux samples. Kim et al (2011) found that farnesene loss rates due to OH and O 3 are on the order of an hour Table 4 Percentage of each compound class (monoterpenes, oxygenated terpenes, and sesquiterpenes) accounted for by individual compounds from the Pinus taeda REA flux data, branch enclosure data: G10gs and G10oth (Geron and Arnts, 2010, growing season and other, respectively), H06 (Helmig et al, 2006), and O08 (Ortega et al, 2008), MEGAN, needle extracts, and the monoterpene review (G2000) by Geron et al (2000a).

“…Δ3-carene was negligible in the emission and extract sources, but is 7-8% in MEGAN. Given that it is only 1% of P. taeda terpene composition in Geron et al (2000aGeron et al ( , 2000b, a reduction in this compound may be warranted in MEGAN. Harley et al (2014) also suggested that a significant non-needle source of Δ3-carene is needed to balance ambient concentrations with its absence in branch enclosure emission measurements from P. ponderosa.…”

“…A flux study at the Prophet research site in Michigan by Karl et al [2003] seems appropriate for comparison with the present data: the forest types in both northern Michigan and New England were characterized as northern mixed and northern coniferous by Geron et al [2000]. The results from Karl et al [2003] are contrasted to those of the present study in Table 4.…”

Budget of organic carbon in a polluted atmosphere: Results from the New England Air Quality Study in 2002

[1] An extensive set of volatile organic compounds (VOCs) and particulate organic matter (POM) was measured in polluted air during the New England Air Quality Study in 2002. Using VOC ratios, the photochemical age of the sampled air masses was estimated. This approach was validated (1) by comparing the observed rates at which VOCs were removed from the atmosphere with the rates expected from OH oxidation, (2) by comparing the VOC emission ratios inferred from the data with the average composition of urban air, and (3) by the ability to describe the increase of an alkyl nitrate with time in terms of the chemical kinetics. A large part of the variability observed for oxygenated VOCs (OVOCs) and POM could be explained by a description that includes the removal of the primary anthropogenic emissions, the formation and removal of secondary anthropogenic species, and a biogenic contribution parameterized by the emissions of isoprene. The OVOC sources determined from the data are compared with the available literature, and a satisfactory agreement is obtained. The observed sub-mm POM was highly correlated with secondary anthropogenic gas-phase species, strongly suggesting that the POM was from secondary anthropogenic sources. The results are used to describe the speciation and total mass of gas-and particle-phase organic carbon as a function of the photochemical age of an urban air mass. Shortly after emission the organic carbon mass is dominated by primary VOCs, while after two days the dominant contribution is from OVOCs and sub-mm POM. The total measured organic carbon mass decreased by about 40% over the course of two days. The increase in sub-mm POM could not be explained by the removal of aromatic precursors alone, suggesting that other species must have contributed and/or that the mechanism for POM formation is more efficient than previously assumed.Citation: de Gouw, J.

Observations of continental biogenic impacts on marine aerosol and clouds off the coast of California

et al. 2014

During the 2011 Eastern Pacific Emitted Aerosol Cloud Experiment (E‐PEACE) and 2013 Nucleation in California Experiment (NiCE) field campaigns, a predominantly organic aerosol (> 85% by mass) was observed in the free troposphere over marine stratocumulus off the coast of California. These particles originated from a densely forested region in the Northwestern United States. The organic mass spectrum resolved by positive matrix factorization is consistent with the mass spectra of previously measured biogenic organic aerosol. Particulate organic mass exhibits a latitudinal gradient that corresponds to the geographical distribution of vegetation density and composition, with the highest concentration over regions impacted by densely populated monoterpene sources. Due to meteorological conditions during summer months, cloud‐clearing events transport aerosol from the Northwestern United States into the free troposphere above marine stratocumulus. Based on the variation of meteorological variables with altitude, dry air containing enhanced biogenic organic aerosol is shown to entrain into the marine boundary layer. Fresh impacts on cloud water composition are observed north of San Francisco, CA which is consistent with fresh continental impacts on the marine atmosphere at higher latitudes. Continental aerosol size distributions are bimodal. Particles in the 100 nm mode are impacted by biogenic sources, while particles in the ∼ 30 nm mode may originate from fresh biogenic emissions. Continental aerosol in the 100 nm mode is cloud condensation nuclei active and may play a role in modulating marine stratocumulus microphysics.
