A methodology for the quantification of the net African dust load in air quality monitoring networks

摘要: This paper proposes and validates a methodology for the quantification of daily African PM load during dust outbreaks in southern Europe. The net PM10 attributable to an episode given region can be obtained by subtracting regional background (RB) level from concentration value at RB station. As demonstrated this paper, applying monthly moving 30th percentile time series station after prior extraction data days with transport. levels subtracted recorded same site only on when occurrence was demonstrated, difference being load. It is thus possible quantify contribution event Europe without need speciation. The validation performed comparing estimated three stations crustal determined chemical speciation filters. correlation (r2>0.6) equivalence (correlation lines’ slopes ∼1) were significant cases.
