### Major: Atmospheric and Oceanic Sciences B.S.

The AOS major is exciting, timely, and relevant. Contact an advisor for more information!

#### Preparation for the Major

- 1 of two Chemistry Sequences:
- Chemistry and Biochemistry sequence for physical scientists: 20A and 20B*
- Chemistry and Biochemistry sequence for life scientists: 14A and 14B

- 1 of two Calculus Sequences:
- Calculus sequence for physical scientists and engineers: Math 31A, 31B, 32A, 32B, 33A, and 33B*
- Calculus sequence for life scientists: Math 3A, 3B, 3C

- 1 of four Physics Sequences:
- Engineering Physics sequence lectures: 1A, 1B, 1C
- Honors Physics sequence lectures: 1AH, 1BH, 1CH
- Life Science Physics sequence lectures: 5A, 5B, 5C

- AOS M71(strongly preferred) or Program in Computing 10A
- AOS 51
- AOS 90

*** 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 31A through 33B 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

**Tracks within the major ** These are unofficial recommendations for which 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 change major.

#### Transfer Students

Transfer applicants to the Atmospheric, Oceanic, and Environmental 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 with laboratory, one general chemistry course with laboratory for majors, and one Matlab, Python, or C++ programming course.

Refer to the UCLA Transfer Admission Guide for up-to-date information regarding transfer selection for admission.

*** Courses taken to fulfill requirements must be taken for letter grades.***

*Any course taken to fulfill major requirements for the AOS major during Spring 2020, Summer 2020, and Fall 2020 can be taken for a letter grade or as Passed/Not Passed. Due to current circumstances related to COVID-19, we hope this temporary change in policy will allow each of our students to choose a grade basis that is most suitable to them.

This temporary change of policy will **only** apply to Spring 2020, Summer 2020, and Fall 2020. It will not apply to any previous or future terms.

For the official requirements, please visit the UCLA Registrar website.
