High temporal resolution measurements of dust composition in the Saharan Air Layer - dataset
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...

| Sumario: | 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. |
