What is it about?
This study consists of a long-term monitoring of Saharan dust outbreaks producing haze that reaches the southern Iberian Peninsula. Aerosol concentration, relative humidity, and temperature time series available at the ground stations in this area indicate sharp variations of these atmospheric variables during the iberulite-forming events. These events mainly occurred during the summer, when it is reached a minimum threshold in the content of large aerosol particles (PM10>15μg×m3).

Why is it important?
Iberulites are the result of the atmospheric scavenging. Until now was unknown that this scavenging could be the responsible of aggregation phenomena, represented by the iberulites. But this only occurs with specific levels of aerosols.
Perspectives
It would be interesting detect this particles in other regions of the world, specially in those with high levels of aerosols.
