“…Franco et al [] report a sharp increase (4.90 ± 0.91% yr −1 ) in measurements of C 2 H 6 columns (molecules cm −2 ) over the Jungfraujoch site in the Swiss Alps between 2009 and 2014. Vinciguerra et al [] also showed a ~25% increase (1.1 ppbv) in hourly mean C 2 H 6 surface mixing ratios from 2004 to 2013 at different sites downwind of the Marcellus shale play, one of the largest natural gas producing regions in the U.S. Several recent field measurement campaigns over U.S. natural gas basins have reported very high average mixing ratios of C 2 H 6 (up to 300 ± 169 ppbv (1 σ ) [ Koss et al , ]), along with other volatile organic compounds (VOCs) [ Gilman et al , ; Helmig et al , ; Katzenstein et al , ; Pekney et al , ; Pétron et al , ; Swarthout et al , ; Thompson et al , ], and several studies have found that C 2 H 6 is the quantitatively largest nonmethane VOC emitted during oil and natural gas exploitation [ Field et al , ; Kort et al , ; Vinciguerra et al , ; Warneke et al , ].…”

Recent measurements over the Northern Hemisphere indicate that the long‐term decline in the atmospheric burden of ethane (C2H6) has ended and the abundance increased dramatically between 2010 and 2014. The rise in C2H6 atmospheric abundances has been attributed to oil and natural gas extraction in North America. Existing global C2H6 emission inventories are based on outdated activity maps that do not account for current oil and natural gas exploitation regions. We present an updated global C2H6 emission inventory based on 2010 satellite‐derived CH4 fluxes with adjusted C2H6 emissions over the U.S. from the National Emission Inventory (NEI 2011). We contrast our global 2010 C2H6 emission inventory with one developed for 2001. The C2H6 difference between global anthropogenic emissions is subtle (7.9 versus 7.2 Tg yr−1), but the spatial distribution of the emissions is distinct. In the 2010 C2H6 inventory, fossil fuel sources in the Northern Hemisphere represent half of global C2H6 emissions and 95% of global fossil fuel emissions. Over the U.S., unadjusted NEI 2011 C2H6 emissions produce mixing ratios that are 14–50% of those observed by aircraft observations (2008–2014). When the NEI 2011 C2H6 emission totals are scaled by a factor of 1.4, the Goddard Earth Observing System Chem model largely reproduces a regional suite of observations, with the exception of the central U.S., where it continues to underpredict observed mixing ratios in the lower troposphere. We estimate monthly mean contributions of fossil fuel C2H6 emissions to ozone and peroxyacetyl nitrate surface mixing ratios over North America of ~1% and ~8%, respectively.

“…In recent decades, stricter regulations by the U.S. Environmental Protection Agency and state agencies have 20 resulted in lower emissions of black carbon, hydrocarbons (including air toxics), and nitrogen oxides in many urban environments (e.g., Parrish et al, 2002;Peischl et al, 2010;Sather and Cavender 2012;Warneke et al, 2012;Zhou et al, 2014;Kirchstetter et al, 2017) while in other areas, both populated and remote, expansion or emergence of new oil and natural gas (O&G) exploration and production activities has led to higher emissions of air toxics, methane, and non-methane hydrocarbons, e.g., C 2 -C 8 and larger alkanes, benzene and larger aromatic species (e.g., 25 Petron et al, 2012;Gilman et al, 2013;Adgate et al, 2014;Helmig et al, 2014;Pekney et al, 2014;Warneke et al, 2014;Field et al, 2015;Koss et al, 2015;Rutter et al, 2015;Swarthout et al, 2015;Helmig et al, 2016;Prenni et al, 2016;Abeleira et al, 2017;Koss et al, 2017). The impact of higher emissions of such hydrocarbons from oil and gas fields of Utah and Wyoming on wintertime ozone has been assessed through recent measurement and modeling studies (Carter and Seinfeld 2012;Edwards et al, 2014;Rappenglück et al, 2014;Ahmadov et al, 2015).…”

2O&G sector using the top-down approach, it was estimated that the O&G sector contributed to <5% of total OA, but up to 38% of anthropogenic SOA in the region. The best agreement between the measured and simulated median OA was achieved by limiting the extent of biogenic hydrocarbon aging and consequently biogenic SOA (bSOA) production. Despite a lower production of bSOA in this scenario, contribution of bSOA to total SOA remained high at 40-54%.

Abstract. The evolution of organic aerosols (OAs) and their precursors in the boundary layer (BL) of the Colorado Front Range during the Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ, July-August 2014) was analyzed by in situ measurements and chemical transport modeling. Measurements indicated significant production of secondary OA (SOA), with enhancement ratio of OA with respect to carbon monoxide (CO) reaching 0.085 ± 0.003 µg m −3 ppbv −1 . At background mixing ratios of CO, up to ∼ 1.8 µg m −3 background OA was observed, suggesting significant non-combustion contribution to OA in the Front Range. The mean concentration of OA in plumes with a high influence of oil and natural gas (O&G) emissions was ∼ 40 % higher than in urban-influenced plumes. Positive matrix factorization (PMF) confirmed a dominant contribution of secondary, oxygenated OA (OOA) in the boundary layer instead of fresh, hydrocarbon-like OA (HOA). Combinations of primary OA (POA) volatility assumptions, aging of semivolatile species, and different emission estimates from the O&G sector were used in the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) simulation scenarios. The assumption of semi-volatile POA resulted in greater than a factor of 10 lower POA concentrations compared to PMF-resolved HOA. Including top-down modified O&G emissions resulted in substantially better agreements in modeled ethane, toluene, hydroxyl radical, and ozone compared to measurements in the high-O&G-influenced plumes. By including emissions from the O&G sector using the topdown approach, it was estimated that the O&G sector contributed to < 5 % of total OA, but up to 38 % of anthropogenic SOA (aSOA) in the region. The best agreement between the measured and simulated median OA was achieved by limiting the extent of biogenic hydrocarbon aging and consequently biogenic SOA (bSOA) production.
