GEO 361/ENV 361/CEE 360/AOS 561 (Fall Semester) (Fueglistaler)

Earth's Atmosphere

This course discusses the processes that control Earth's climate - and as such the habitability of Earth - with a focus on the atmosphere and the global hydrological cycle. The course balances overview lectures (also covering topics that have high media coverage like the 'Ozone hole' and 'Global warming', and the impact of volcanoes on climate) with selected in-depth analyses. The lectures are complemented with homework based on real data, demonstrating basic data analysis techniques employed in climate sciences.

GEO 425/MAE 425 (Fall Semester) (Vecchi)

Introduction to Physical Oceanography

The study of the oceans as a major influence on the atmosphere and the world environment. The theoretical and observational bases of our understanding of ocean circulation and the oceans' properties. The Coriolis-dominated equations of motion, atmospheric and upper oceanic Ekman layers, the thermocline, wind-driven and thermohaline-driven circulation, oceanic tracers, waves, and tides.

GEO 427 (Fall Semester - (Delworth)

Fundamentals of the Earth's Climate System

The goal of the course is to provide students with an introductory overview of the broad factors that determine our current climate, as well as past and future climates. We first build a foundation for understanding the principal features of today's climate. This includes examining the Earth's energy and water cycles, the processes determining the principal atmospheric and ocean circulation features, climate feedback processes, and dominant modes of variability. We then use this framework to interpret observational records of past climates, including ice age cycles, and to examine projections of future climate change.

GEO 503/AOS 503

Responsible Conduct of Research in Geosciences (Half-Term)
Course educates Geosciences and AOS students in the responsible conduct of research using case studies appropriate to these disciplines. This discussion-based course focuses on issues related to the use of scientific data, publication practices and responsible authorship, peer review, research misconduct, conflicts of interest, the role of mentors & mentees, issues encountered in collaborative research and the role of scientists in society. Successful completion is based on attendance, reading, and active participation in class discussions. Course satisfies University requirement for RCR training.

AOS 523 (Spring Semester) (Fueglistaler)

Water in the Atmosphere

Despite the paramount importance of atmospheric water vapour for climate, our understanding of the processes that regulate its distribution and changes therein in a changing climate, remains incomplete.  This course analyses observations and discusses theoretical approaches, both basic concepts and novel ideas, to the problem.
