“…Previous atmospheric chemistry studies at the site and in surrounding regions include investigations on the variability of surface ozone under a mesoscale circulation and in the cities of Huelva and Seville (Adame et al, 2008;Adame et al, 2010a;Adame et al, 2010b). Alastuey et al (2006) performed chemical characterization of particulate matter sources in south west Spain while more recently, Diesch et al (2012) studied the variability of aerosol, gaseous pollutants and meteorological characteristics associated with changes in air mass origin during the DOMINO campaign and found significantly higher fraction of aged organics in submicron aerosol particles sampled in air masses from the continental sector, when compared with air masses from other wind sectors. Direct OH reactivity measurements were made during DOMINO using the comparative reactivity method described by Sinha et al (2008).…”

Abstract. In this study air masses are characterized in terms of their total OH reactivity which is a robust measure of the "reactive air pollutant loading". The measurements were performed during the DOMINO campaign (Diel Oxidant Mechanisms In relation to Nitrogen Oxides) held from 21/11/2008 to 08/12/2008 at the Atmospheric Sounding Station -El Arenosillo (37.1 • N-6.7 • W, 40 m a.s.l.). The site was frequently impacted by marine air masses (arriving at the site from the southerly sector) and air masses from the cities of Huelva (located NW of the site), Seville and Madrid (located NNE of the site). OH reactivity values showed strong wind sector dependence. North eastern "continental" air masses were characterized by the highest OH reactivities (average: 31.4 ± 4.5 s −1 ; range of average diel values: 21.3-40.5 s −1 ), followed by north western "industrial" air masses (average: 13.8 ± 4.4 s −1 ; range of average diel values: 7-23.4 s −1 ) and marine air masses (average: 6.3 ± 6.6 s −1 ; range of average diel values: below detection limit −21.7 s −1 ), respectively. The average OH reactivity for the entire campaign period was ∼18 s −1 and no pronounced variation was discernible in the diel profiles with the exception of relatively high values from 09:00 to 11:00 UTC on occasions when air masses arrived from the north western and southern wind sectors. The measured OH reactivity was used to constrain both diel instantaneous ozone production potential rates and regimes. Gross ozone production rates at the site were generally limited by the availability of NO x with peak values of around 20 ppbV O 3 h −1 . Using the OH reactivity based approach, derived ozone production rates indicate that if NO x would no longer be the limiting factor in air masses arriving from the continental north eastern sector, peak ozone production rates could double. We suggest that the new combined approach of in-situ fast measurements of OH reactivity, nitrogen oxides and peroxy radicals for constraining instantaneous ozone production rates, could significantly improve analyses of upwind point sources and their impact on regional ozone levels.

“…The hourly contribution matrix G (i.e., g ip in Eq. (1)) was generated by using average contributions (Table S1 in the Supporting Information) that were available in the literature (Zheng et al, 2002;Lee et al, 2003;Kim et al, 2005;Marmur et al, 2005;Alastuey et al, 2006;Hopke et al, 2006;Kulkarni et al, 2007;Song et al, 2008;Yuan et al, 2009;Chan et al, 2011;Guo et al, 2011). Next, hourly fluctuations were added by assuming random variability and a lognormal distribution (Lingwall and Christensen, 2007) for each source, except for vehicle exhaust.…”

This study was conducted to evaluate the performance of an improved source apportionment model that is suitable for incorporating data with multiple time resolutions. This evaluation was achieved by using synthetic data sets that simulated environmental concentrations of volatile organic compounds (VOCs) and fine particulate matter (PM 2.5 ) from the five following sources: petroleum refinery, vehicle exhaust, industrial coating, coal combustion, and natural gas. Hourly VOCs and speciated PM 2.5 data were simulated for a one-week period. The PM 2.5 data were further averaged every twelve hours to generate data sets with mixed temporal resolutions. The Multilinear Engine program was applied to resolve the source profiles and contributions. A series of sensitivity analyses was conducted to examine how uncertainties in the profile variation, measurement error, and source collinearity affected the model performance. The resolved factor profiles closely matched the input profiles, and the measurement error had a larger impact on the modeling results than the profile variation. In the most comprehensive data set that contained all three types of uncertainty, the R 2 values between the input and retrieved source contributions were between 0.87 and 0.95. The estimated percentage contributions were also comparable with the input ones, demonstrating the applicability and validity of this improved model.

Abstract. Measurements of the ambient aerosol were performed at the Southern coast of Spain, within the framework of the DOMINO (Diel Oxidant Mechanisms In relation to Nitrogen Oxides) project. The field campaign took place from 20 November until 9 December 2008 at the atmospheric research station "El Arenosillo" (37 • 5 47.76 N, 6 • 44 6.94 W). As the monitoring station is located at the interface between a natural park, industrial cities (Huelva, Seville) and the Atlantic Ocean, a variety of physical and chemical parameters of aerosols and gas phase could be characterized in dependency on the origin of air masses. Backwards trajectories were examined and compared with local meteorology to classify characteristic air mass types for several source regions. Aerosol number and mass as well as polycyclic aromatic hydrocarbons and black carbon concentrations were measured in PM 1 and size distributions were registered covering a size range from 7 nm up to 32 µm. The chemical composition of the non-refractory submicron aerosol (NR-PM 1 ) was measured by means of an Aerosol Mass Spectrometer (Aerodyne HR-ToF-AMS). Gas phase analyzers monitored various trace gases (O 3 , SO 2 , NO, NO 2 , CO 2 ) and a weather station provided meteorological parameters.Lowest average submicron particle mass and number concentrations were found in air masses arriving from the Atlantic Ocean with values around 2 µg m −3 and 1000 cm −3 . These mass concentrations were about two to four times lower than the values recorded in air masses of continental and urban origins. For some species PM 1 -fractions in marine air were significantly larger than in air masses originating from Huelva, a closely located city with extensive industrial activities. The largest fraction of sulfate (54 %) was detected in marine air masses and was to a high degree not neutralized. In addition, small concentrations of methanesulfonic acid (MSA), a product of biogenic dimethyl sulfate (DMS) emissions, could be identified in the particle phase.In all air masses passing the continent the organic aerosol fraction dominated the total NR-PM 1 . For this reason, using Positive Matrix Factorization (PMF) four organic aerosol (OA) classes that can be associated with various aerosol sources and components were identified: a highlyoxygenated OA is the major component (43 % OA) while semi-volatile OA accounts for 23 %. A hydrocarbon-like OA mainly resulting from industries, traffic and shipping emissions as well as particles from wood burning emissions also contribute to total OA and depend on the air mass origin.A significant variability of ozone was observed that depends on the impact of different air mass types and solar radiation.
