The Program offers a wide variety of courses in Atmospheric and Oceanic Sciences. These courses are designed to help students understand the fundamentals and to expose them to the advanced research topics in the field. In addition, students have opportunities to take courses offered by other departments and programs (e.g., Applied and Computational Mathematics, Physics, Ecology and Evolutionary Biology).
GEO 361/ENV 361/CEE 360/AOS 561 (Fall Semester) (Fueglistaler)
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.

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.

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.

Atmospheric Radiative Transfer
The structure and composition of terrestrial atmospheres. The fundamental aspects of electromagnetic radiation, absorption and emission by atmospheric gases, optical extinction by particles, the roles of atmospheric species in the Earth's radiative energy balance, the perturbation of climate due to natural and anthropogenic causes, and satellite observations of climate systems are also studied.

Atmospheric Thermodynamics and Convection
The thermodynamics of water-air systems. The course gives an overview of atmospheric energy sources and sinks. Planetary boundary layers, closure theories for atmospheric turbulence, cumulus convection, interactions between cumulus convection and large-scale atmospheric flows, cloud-convection-radiation interactions and their role in the climate system, and parameterization of boundary layers and convection in atmospheric general circulation models are also studied.

Deep Learning in Geophysical Fluid Dynamics
This reading course provides a survey of the rapidly growing field of physics-informed deep learning, which integrates known physics principles with neural networks to predict the behavior of a physical system. This course both introduces the background knowledge required to implement physics-informed deep learning and provides practical in-class coding exercises. The aim of this course is for students to gain experience applying this emerging method to their own research interests, including topics in geophysical fluid dynamics (atmospheric, oceanic or ice dynamics) or other nonlinear systems where the same technique applies. Students are expected to develop individual projects throughout the semester.
