Environmental Physics
A.Y. 2024/2025
Learning objectives
Students are introduced to the application of physics to environmental problems (from climate change to air pollution). In addition, the course deals with state-of-the-art experimental and modelling approaches widely used in the environmental research field. The main goal of the course is to draw students to the complexity and multi-disciplinary character of the applications of physics to the study of the environment and processes governing it.
Expected learning outcomes
At the end of the course, students:
1. will be able to discuss about environmental issues related to the atmosphere using the correct scientific approach and dealing with the multiple interactions among different components and formation/transformation/deposition processes;
2. will be able to describe physical-chemical processes underlying the themes of interest (E.g. greenhouse effect, ozone hole, photochemical smog, atmospheric aerosols, ) both in terms of their phenomenology and using proper theory;
3. will know experimental methods and principles of operation to characterise physical-chemical-optical properties of atmospheric components;
4. will know basic principles of modelling approaches to study and forecast atmospheric pollutants.

Assessment methods and Criteria
The oral exam will last 1 hour (approx). The knowledge related to the variety of scientific topics faced during the course will be verified together with the theoretical approach and the experimental techniques widely used to study specific processes/parameters. In detail, the comprehension of the complex system "atmosphere", the physics underneath the phenomena of interest, and the ability of explaining the inter-relation among different topics approached during the course will be checked.
