“…Different trajectory statistics methods have been used to reveal the region sources of sulphur oxides and sulphates (Ashbaugh, Malm, and Sadeh 1985;Rúa et al 1998;Zhao, Hopke, and Zhou 2007;Stohl 1996;Poirot and Wishinski 1986), nitrogen oxides and nitrates (Rúa et al 1998;Zhao, Hopke, and Zhou 2007), ozone (Wotawa, Kröger, and Stohl 2000), acid precipitations (Charron et al 2000), aerosol (Seibert et al 1994;Wang, Zhang, and Arimoto 2006;Chen et al 2011;Zhou, Hopke, and Liu 2004;Zhao and Hopke 2006;Tositti et al 2013;Xu et al 2013;Aher et al 2014), sources and sinks of CO 2 (Apadula et al 2003), radioactive Ве 7 (Lee et al 2004), soot particles (Sharma et al 2006), and persistent organic pollutants (Du and Rodenburg 2007;Hsu, Holsena, and Hopke 2003;Sofuoglu et al 2013) in different areas of the planet.…”

A concentration-weighted trajectory method for aerosol source localization based on joint statistical analysis of aerosol column volume concentrations and back-trajectory data was used to estimate the spatial distribution of aerosol sources in the EastEuropean region. The aerosol column volume concentration data measured at five AERONET network sites, Belsk, Minsk, Kyiv, Moldova/Kishinev, and Sevastopol, were used. The geographical areas responsible for increased aerosol content at the monitoring sites were mapped separately for coarse-mode and fine-mode aerosol fractions. The investigated area is located between 42°and 62°N in latitude and between 12°and 50°E in longitude.It was shown that the northeastern territories (in relation to the monitoring stations) give a small contribution to the coarse-mode aerosol content. The events of increased coarse-mode aerosol concentration have been caused by sources in the southeastern regions. On average, the air masses with a large content of coarse-mode aerosol particles were delivered to all stations from regions around Donetsk, Rostov-on-Don, and Kharkiv cities. The fine-mode aerosol fraction originated from areas of Tambov, Voronezh, and Kharkiv cities. The calculated aerosol source regions partly correspond to European Monitoring and Evaluation Programme data for eastern Europe. The cause of difference between calculated regions responsible for increased aerosol content at the monitoring sites and the sources of particle emission according to European Monitoring and Evaluation Programme data are discussed.

“…6,7 Another characteristic of aerosols in southern Europe is the influence of the African dust outbreaks on PM levels and composition. [8][9][10][11][12] African dust can react with local anthropogenic pollutants, favouring the formation of secondary particles. 13 Furthermore, the high frequency of the re-circulatory air masses in these latitudes during the warm season [14][15][16] plays an important role in the ageing of air masses, affecting the composition and levels of PM.…”

Characterization of a long range transport pollution episode affecting PM in SW Spain

et al. 2008

A multidisciplinary study on aerosol characterization was performed at the regional background monitoring station of El Arenosillo, in SW Spain, between 28 June and 5 July 2006. The main aim of the Arenosillo aerosol measurement campaign 2006 was to compare the results of aerosol characterization obtained by different groups by measuring physical and chemical parameters using optical methods and in situ sampling. The campaign coincided with a long-range transport episode from Western Iberia, passing through the Gulf of Cadiz and the Straits of Gibraltar towards the study area. The results of the variability of PM levels and chemical composition of PM10, PM2.5 and PM1 at El Arenosillo and at three nearby regional and urban background sites were interpreted. Mean levels measured during the campaign reached 23, 15 and 12 microg m(-3) for PM10, PM2.5 and PM1, respectively, at El Arenosillo. PM during the Arenosillo campaign 2006 was dominated by the secondary inorganic aerosols (SIA, 24, 38 and 39% of PM10, PM2.5 and PM1 mass), carbonaceous aerosols (17, 21 and 23% of the mass), crustal material (13, 9 and 4%), and sea spray (10, 5 and 1%). These values are within the usual range of regional background sites of Southern Spain with the exception of the relatively low crustal load and the high SIA levels. Two major PM episodes were differentiated. The first one was characterized by high levels of Bi, As, Pb, Se, P and Zn, which are the main tracers of the industrial emissions near the town of Huelva. High concentrations of these elements were also recorded at the nearby sites. In the second episode, maximum levels of SO4(2-), V and coarse Cu as well as the bulk mass of PM1 were determined, tracing the polluted air mass transport from Western Iberia through the Straits of Gibraltar. These results underline the importance of the influence of long-range transport of pollutants on the levels and composition of regional background PM in SW Iberia, where local emissions may also play a role.

“…In this study we used statistical tools and information about the trajectories by means of the CPF functions. A good summary of this technique is given by Gebhart and Malm [6] and examples of their use in Spain can be found for sources of wet deposition of majorions [16][17][18], for sources of SO 2 , NO X , SO^~ and NO 3 [3,19,20] and for study of the sources of surface ozone in Spain [21]. (Figure 1), six stations belonging to EMEP network.The EMEP stations have the following characteristics: They must be placed in rural areas, away from building areas.…”

In this study we analyze the temporal evolution of the suspended particulated matter (SPM) in the air of the six Spanish remote stations belonging to the European Monitoring and Evaluation Programme network. A negative trend is observed in three of them and a positive trend in one. Another objective of this work was to know the geographical sources of SPM in Spain. To do this we used the conditional probability functions (cf. Ashbaugh et al. (1985), Atmos. Environ., 19, 1263Environ., 19, -1270 and information about air masses trajectories. The North of Africa and regions inside Spain are the main sources while Continental Europe and the British Islands are less important.
