Per la serie dei seminari di meteorologia ambientale dell’Università di Trento, Giovedì 23 novembre alle ore 14:30 il dott. Claudio Mazzoleni, docente di Atmospheric Sciences Program della Michigan Technological University terrà il seminario dal titolo: Light Absorbing Aerosols: Properties, Measurements, and Effects on Climate.
Il seminario si svolgerà in presenza presso la lecture room 1P (1st floor) – DICAM – dell’Università di Trento in Via Mesiano 77 oppure in streaming online al seguente link ZOOM: https://unitn.zoom.us/j/86983071443 (Meeting ID: 869 8307 1443, Passcode: 482285)
Vi riportiamo un abstract del seminario e la biografia del docente Claudio Mazzoleni
Abstract Atmospheric particles are incredibly diverse in terms of their physical and chemical properties. We typically refer to the suspension of these particles in the atmosphere as “aerosols”. The physical and chemical properties of aerosols determine their lifecycle and climatic and air quality impacts. These properties include particle size, chemical composition, and affinity for water, which determines their ability to interact with water vapor and clouds. Additionally, when looking under an electron microscope, one sees that these particles have very different shapes, and several components can mix with different geometrical structures. These additional geometrical and topological properties also affect how the particles transform in the atmosphere, and how they interact with solar radiation and clouds. Eventually, these interactions determine their optical properties and finally their warming or cooling potentials. In this seminar, I will talk about a particular category of atmospheric particles, namely, light-absorbing aerosols. These particles in addition to scattering the solar radiation also absorb it. I will also discuss how one can measure some of the properties of these particles and the associated challenges. I will conclude my talk by providing a brief overview of our atmospheric sciences program and some of the current research fields at Michigan Technological University. Bio Claudio Mazzoleni is a Professor in the Physics Department and the Atmospheric Sciences Program at Michigan Technological University, where he started his academic career in 2008. He earned a Laurea in Physics in 1995 at the University of Trento, Italy, and a Ph.D. in Atmospheric Sciences in 2003 at the Desert Research Institute of Reno, NV. He was a post-doc at the Los Alamos National Laboratory from 2005 to 2008. He is currently on sabbatical leave in Europe. His research focuses on the study of atmospheric particles with an emphasis on their optical and morphological properties.
