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.

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 - alternate years, next taught in Fall 2021) (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.

Southern Ocean Seminar
The Southern Ocean is central to many questions regarding global climate and environmental conditions. The course reviews and evaluates the field's current understanding of the Southern Ocean: its modern processes, physical, chemical, and biological; its geologic origins; its evolution through geologic time and over orbital cycles; and predictions for its future. The course is composed of introductory lectures, topical presentations by members of Princeton University's academic community, and student-led presentations that draw from recent and ongoing research.

The Physics of Glaciers
Glaciers and ice sheets are important elements of Earths global climate system. This course introduces graduate students to the history of ice on Earth, contemporary glaciology, and the interactions between climate, glaciers, landforms, and sea level. Drawing from basic physical concepts, lab experiments, numerical modeling, and geological observations, we tackle important physical processes in glaciology, and equip students with data analysis and modeling skills. Students gain an appreciation for the importance of ice sheets for the global climate system, and the large gaps that remain in our understanding.

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.
