College of Natural Sciences and Mathematics >Department of Earth and Atmospheric Sciences >Atmospheric Sciences, PhD
A doctoral applicant will have earned a Master’s degree or have completed 30 semester hours of graduate credit, and submitted scores from the General GRE examination (verbal, quantitative, and analytical writing); advanced GRE is recommended but optional. GRE score must be at least 1100 for verbal and math sections together and 3.0 for analytical writing. TOEFL examination is required for all non-native English-speaking students and the lowest score accepted is 550 for the paper version and 213 for the computer-based examination. The Director of Graduate Studies in Atmospheric Science and Chairman will evaluate the credentials of each applicant for the Ph.D. program, considering a broad range of criteria, including:
- Content of undergraduate and graduate programs and grades earned, particularly in the areas of Meteorology, Physics, Mathematics, Chemistry, Geosciences, or related natural/physical sciences.
- Letters of recommendation from three (3) individuals (preferably faculty members), who are able to judge the candidate’s academic abilities and potential for scholarly research.
- Scores earned on the General GRE test (and TOEFL test, where applicable).
- Scientific, professional, and technical publications, and Master’s Thesis.
The award of the Doctorate of Philosophy degree signifies that the recipient has achieved broad knowledge of the discipline and demonstrated research competence meeting national standards through completion of an acceptable dissertation.
During the week before their first full semester at the University, the student must take a Departmental general Placement Examination, consisting of both written and oral parts. Students wishing to qualify for candidacy for the Ph.D. degree in Atmospheric Science must demonstrate general proficiency in mathematics, physics, and chemistry (when atmospheric chemistry is the chosen area of specialty). Some graduate courses explicitly require prerequisite courses, e.g., MATH 3363, MATH 2331, MATH 2433, GEOL 3378, GEOL 3342 or their equivalent at other institutions. The examining committee will determine what deficiencies - if any - are present, and the acceptable means of removing those deficiencies (e.g., course work within and/or outside the Department, directed study, research papers).
The first year of studies will concentrate on courses in the expected area of research, as well as courses needed to remove deficiencies. During the first year, the student is expected to have selected a Dissertation Advisor and constituted his/her Dissertation Committee to reflect research interests. It is assumed that the student will complete most course work during this first year of study. The second year will consist of additional course work, where necessary, research, and final preparation for the Candidacy Examination and the presentation of the Dissertation Proposal. The oral Candidacy Examination and Dissertation Proposal should be completed during the third semester for full-time students, or before completion of five semesters for part-time students. Upon successful presentation of the research proposal, the applicant will be granted Ph.D. Candidacy status.
Sequence and Timing
- Prior to first full semester in Ph.D. program:
- Departmental Placement Examination.
- Appropriate course work.
- Removal of all deficiencies.
- Establishment of Ph.D. Research Committee.
- Taking the Candidacy Exam and presenting the Dissertation Proposal during the first semester of the second year.
- Completion of all formal course work.
- Initiation of research.
- Third and successive years:
- Submission of a manuscript to a peer-reviewed journal
- Completion and defense of dissertation.
Financial Support for Students in the Doctoral Program
In accordance with University regulations, a student accepted into the program and offered Departmental support (e.g., Teaching Assistantship (TA) or Research Assistantship (RA)) may receive such support for up to 10 long semesters (5 years) provided the student is deemed to be making adequate progress toward the degree and such resources are available. It is the goal of the department for students to finish their degree within the shortest possible time consistent with the completion of an acceptable dissertation. Students must be registered as full-time students and may not hold any additional employment while holding a TA or RA.
Progress toward the degree will normally be measured in terms of course work (maintaining at least a B average), elimination of deficienciesand timely selection of a Dissertation Committee, completion of requirements for Candidacy and presentation of a Dissertation Proposal. After the first two semesters, progress will be evaluated and continued support will be granted on the basis of a favorable review and availability of resources. In each subsequent semester, the Dissertation Committee will review the student’s progress, inform the student of their findings, and place a statement in the student’s departmental file.
