Natural gas phase and heterogeneous chemistry in the troposphere and stratosphere, with a focus on elementary chemical kinetics; photolysis processes; oxygen, hydrogen, and nitrogen chemistry; transport of atmospheric trace species; tropospheric hydrocarbon chemistry and stratospheric halogen chemistry; stratospheric ozone destruction; local and regional air pollution, and chemistry-climate interactions are studied.

Thermodynamics of water-air systems. 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.

Observational evidence of atmospheric and oceanic waves; laboratory simulation. Surface and internal gravity waves; dispersion characteristics; kinetic energy spectrum; critical layer; forced resonance; instabilities. Planetary waves: scale analysis; physical description of planetary wave propagation; reflections; normal modes in a closed basin. Large-scale barclinic and barotropic instabilities. Eady and Charney models for barclinic instability, and energy transfer.

Each week, students read one research paper and discuss with faculty. The instructor provides additional information such as the historical context, motivation of research, and impact on the field. The papers selected differ from year to year, with a semester's papers organized around either: a collection of "great papers" that are seminal in the field of AOS; a collection of recent high impact papers; and papers discussing a specific topic. The detailed analysis of the research papers also helps students familiarize with the process of distilling essential results for publication.

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.
