Lecture
This lecture by the instructor focuses on the research conducted at the Extreme Environments Research Laboratory, which specializes in studying regions like the Antarctic, Arctic, Southern Ocean, and the Alps due to their sensitivity to climate change. The lecture delves into the measurement and modeling of atmospheric processes, including chemical composition, microphysics, and cloud processes, emphasizing their impact on Earth's radiative balance and climate change. The instructor explains the complex interactions in polar regions, where feedback loops play a crucial role in understanding how different elements like land, ocean, and cryosphere influence the atmosphere's composition and, consequently, climate. The lecture also covers the methodologies employed, such as conducting measurements in remote areas, utilizing tethered balloon systems for vertical profiling, and analyzing data post-fieldwork to comprehend its implications.
