Expertise

atmospheric science, aerosol-cloud interactions, climate change in polar regions

Mission

Extreme environments are particularly sensitive to climate change and are transforming at accelerated rates. This can have important global repercussions. EERL aims to create integrated process understanding by investigating interactions between the atmosphere, cryosphere, biosphere, ocean, land and anthroposphere. The goal is to characterize climate-change relevant and vertically-resolved processes that are directly influenced by humans, and natural processes that are simultaneously undergoing change due to climate forcing. The enhanced process understanding will enable us to better simulate the fate of extreme environments in the context of global change and resulting implications for society.

Courses

Physics and chemistry of the atmosphere

ENV-320

The course provides an introduction to the physical and chemical processes that govern the atmospheric dynamics at small and large scales. The basis is laid for an in depth understanding of our atmospheric environment and the climate system.

Science of climate change

ENV-410

The course equips students with a comprehensive scientific understanding of climate change covering a wide range of topics from physical principles, historical climate change, greenhouse gas emissions, the IPCC assessment to future scenarios and climate action.
