Lehrinhalt

This lecture introduces all physical concepts of the fundamentals of Environmental Physics and it is accompanied by exercises and tutorials every week.
The content spans:
• The fundamentals about the Earth climate system and its compartments, flow, transport, and the global radiation balance.
• Geophysical fluid dynamics, i.e. the fundamental laws of free and forced fluid movement and vorticity, and a practical guide to the first principles of turbulence.
• Global circulation of atmosphere and ocean, boundary layer physics, and slow flow through porous media and of ice.
• Gas and heat exchange between ocean and atmosphere. Global fluxes and cycles (energy, water, carbon).
• Isotope fractionation and isotope methods to study the Earth environments, focus on water and carbon isotopes.
• Introduction to models of environmental systems, basic principles of numerical climate modelling.
• Basic principles of radiative transfer. Climate system radiative forcing and sensitivity. Global climate change past, present and future.

Lehrziel

Students achieve a fundamental understanding of the key physical processes and interactions in the Earth surface system and its compartments, as well as of the human impact on these systems and the related societal implications. They are able to solve basic problems of environmental physics and interpret the results in the context of fundamental questions regarding the physics of the earth surface environments and the methodologies to observe and study those.
