Roberto Salzano obtained his PhD in Geodynamics from the Roma TRE University, Italy. He is currently working as a Researcher at the Italian National Research Council. He joined the Division of Florence of the Institute of Atmospheric Pollution Research in 2014. His research mainly focuses on the dynamics at the air-ground interface, particularly focused on different types of surfaces (soil, rock, snow, etc.). He has been involved in several research projects in the field of atmospheric pollution in urban and remote regions, as well as cold regions (Arctic, Antarctica, and the Alps). Furthermore, his main topic is the relationship between processes occurring at the air–ground interface and the optical behavior of the surface.
