This dataset contains observations of elemental composition of atmospheric aerosols performed at Izaña Observatory, located (28◦18’N, 16◦29′W) at 2367 m.a.s.l. (meters above sea level), in Tenerife island. The measurements were performed with the objective of studying the variability of Saharan dust composition. The samples were analyzed with the technique PIXE (Particle Induced X ray Emission) at the Istituto Nazionale di Fisica Nucleare (INFN) at Florence (Italy). The variability of dust composition is compared with the variability of large-scale meteorology traced with the North African dipole Intensity (NAFDI), i.e. the differences of the anomaly of the geopotential heights at 700hPa between the subtropic (Morocco) and the tropic (Niger) in North Africa., This dataset was obtained within the frame of the projects POLLINDUST (reference CGL2011-26259) and AEROATLAN (reference CGL2015-66299-P), funded by the Minister of Economy and Competitiveness of Spain and by the European Regional Development Fund., Sheet <01-aerosols 2010, Sheet <02-NAFDI 2010>, Sheet <03-aerosols 2013>, Sheet <04-NAFDI 2013>., Peer reviewed
