### Major: Atmospheric, Oceanic, and Environmental 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; and labs: 4AL, 4BL*
- Honors Physics sequence lectures: 1AH, 1BH, 1CH; and labs: 4AL, 4BL
- Life Science Physics sequence lectures: 6A, 6B, 6C (phased out in Spring 2018)
- Life Science Physics sequence lectures: 5A, 5B, 5C (effective Fall 2017)

- Earth, Planetary, and Space Sciences 71 (preferred) or Civil and Environmental Engineering M20 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. AOES 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, which we hope to be able to announce later in the 2017-2018 academic year.

#### 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.
