The Doctor of Philosophy (Ph.D.) degree is primarily a research degree. The candidate must complete at least 36 units of graduate course credit in the major field, including a core of 6 units of dynamic meteorology and 6 units of physical meteorology. An additional 18 units of other graduate-level atmospheric sciences courses and 6 units of graduate-level elective coursework completes the 36 credit requirement. In addition, the candidate must complete 18 units of dissertation credit, 2 units of ATMO seminar, and fulfill the minor requirement (typically 12 units, depending on the minor Department). All Ph.D. students must pass a written and oral Comprehensive Examination, and complete and defend a dissertation based on original research.
Students accepted into the graduate program without a Master's of Science (M.S.) degree must first successfully complete the M.S. program before proceeding with the Ph.D. Students entering the Ph.D. program with an M.S. degree in another field are permitted to minor within the department with the approval of their committee. This minor will consist of 12 units of atmospheric sciences at the graduate level in subjects other than those directly related to their area of research.
The program is highly quantitative, it is required for applicants to have a strong background in physics and calculus.

All students must demonstrate competence in statistics and computer programming (e.g. FORTRAN, MatLab, GrADS, NCL), numerical atmospheric models and specialized instrumentation. Participation in laboratory or field work may be a component. Competence may be demonstrated by successful completion of approved courses in these subjects (undergraduate or graduate level).
All students must present the results of their research in a formal seminar or presentation at a scientific meeting in the form of an oral or poster presentation. Typically, students present at the HAS annual student research conference, El Día del Agua y la Atmósfera (Spring Semester) or at AGU (December) or AMS (January) meetings.
