Trends of particulate matter (PM₂.₅) and chemical composition at a regional background site in the Western Mediterranean over the last nine years (2002-2010)
The time variability and long term trends of PM₂.₅ (particulate matter of diameter <2.5 μm) at various regional background (RB) sites across Europe are studied and interpreted in this work. Data on mean annual levels of PM₂.₅ measured at Montseny (MSY, North East Spain) and various RB sites in Sp...
