* Students interested in pursuing graduate studies in atmospheric and oceanic sciences or obtaining employment with the National Weather Service or other governmental agencies are strongly urged to select the Mathematics 31, 32, AND 33 sequence and the Physics 1 sequence.
For petition requests relating to prerequisite and/or major requirements, such as substituting AOS 51 and 90 for similar upper division classes, please consult your departmental advisor.
AOS Program Plan These are recommendations on how to plan out your study list as either a freshman or transfer student. The sample plan only includes major requirements. Each student’s actual study list may differ, and we strongly advise students to work with academic counselors from CAAC and their home department to determine a personal program plan.
Tracks within the major
These are unofficial recommendations for courses to select based on your interests. AOS majors are not required to choose or follow a track. These documents are purely designed to provide guidance on selection of (mostly UD) courses.
We recommend that students that are primarily interested in climate and climate change pursue the climate science major.
Transfer Students
Transfer applicants to the Atmospheric and Oceanic Sciences major with 90 or more units must complete as many of the following introductory courses as possible prior to admission to UCLA: one year of calculus, one year of calculus-based physics, one semester of general chemistry.
Recommended before transfer for timely degree completion: one additional semester of general chemistry and one course in computer programming (preferably in Python).
Refer to the UCLA Transfer Admission Guide for up-to-date information regarding transfer selection for admission.
