Atmospheric Science B.S.

Earth and atmospheric scientists are curious and passionate about the Earth. They are stewards of the Earth’s resources from soils to oceans, atmosphere, and land.

The Department of Earth and Atmospheric Sciences is home to a close-knit group of faculty, staff, and students who are continuously engaged with one another in the study of their discipline. Full time faculty teach all courses in the department. Small class sizes have led many students to describe the department as a "small college environment in a large research university."

The Department of Earth and Atmospheric Sciences offers three degrees: the Bachelor of Science in Earth Science (B.S.), the Bachelor of Arts in Earth and Atmospheric Sciences (B.A.), and the Bachelor of Science in Atmospheric Science (B.S.). The three degrees begin with similar coursework, so it is easy to change your path as your interests develop.

Atmospheric Science is the study of meteorology and climate.

  • Meteorology is the focused study of short-term changes in the weather within the stratosphere and troposphere.
  • Climate science concentrates on longer periods of time, from one month to millions of years. Its object is to describe the interaction of the atmosphere with the surface of the earth: oceans, lakes, land, and glaciers.

The Atmospheric Science B.S. major requires study in earth and atmospheric processes as well as calculus, physics, chemistry, biology, and advanced work in the life and physical sciences.

A degree in Atmospheric Sciences will position you to address such pressing issues as renewable energy and natural resources, environmental pollution, global climate change (especially warming), severe weather and its consequences, and natural hazard assessment and preparedness (earthquakes, volcanoes, hurricanes, and tornadoes, for example).



Getting started

 Atmospheric Science majors begin with the following courses:

  • One of the following courses:
  • An Earth Science elective (see major requirements in your Academic Bulletin)
  • CHEM-C 117 and C 127
  • MATH-M 211 and M 212

For success, it is important to not take too many math/science classes your first two semesters. Please consult with your academic advisor about how to balance your schedule.

Tracks and concentrations

Students majoring in Earth and Atmospheric Sciences have three degree options: Earth and Atmospheric Sciences B.A., Earth Science B.S. and Atmospheric Science B.S. There is also an Atmospheric Sciences Certificate. Your introductory courses will help you decide which path is best for you. Contact the Earth and Atmospheric Sciences academic advisor to discuss these options.

Upper level coursework

Your coursework will continue with 18 hours in upper division courses in atmospheric science. These studies include courses in meteorology, weather analysis and forecasting, instrumentation, dynamic meteorology, synoptic meteorology, air pollution, wind power hydrometeorology, micrometeorology, and climate change. See the Academic Bulletin for more details. You will also complete coursework in physics and additional coursework in outside sciences.

All Atmospheric Sciences students are encouraged to participate in research as part of their undergraduate studies and work with a faculty member on a specific project. Students have the option of taking EAS-X 498 for undergraduate research.

Students with senior standing who are pursuing departmental Honors typically enroll in EAS-E 499 and prepare a written thesis under the supervision of a faculty supervisor.

Commonly pursued majors, minors and certificates

With the help of your academic advisor, you may be able to pursue other areas of interest by completing other majors, minors, or certificates.

Earth and Atmospheric Science students often pursue minors or dual degrees in Anthropology, Astronomy, Biology, Chemistry, Math, or Physics. You may also have interest in completing a minor from the School of Public and Environmental Affairs. The Department of Geography offers a Certificate in GIS and Remote Sensing

Check your Bulletin for a comprehensive listing of majors, minors, and certificates.


Enhance your major

Working with faculty

When pursuing an Atmospheric Science degree, you have the opportunity to work with faculty who have expertise and experience in their fields of study. Take advantage of office hours to talk with your instructors about your performance in class, the content of readings and assignments, and how the course helps you work toward your goals.

Atmospheric Science is a field with a large focus on research. All Atmospheric Science students are encouraged to work with faculty on research during their undergraduate career.

You can get involved in research as early as your freshman year. Many incoming freshmen apply to the Arts and Sciences Undergraduate Research Experience (ASURE) program. ASURE students experience project-based learning enhanced by a community of supportive faculty and peers. Choose an ASURE path in the arts and humanities, social and historical studies, or natural and mathematical sciences. Consider joining one that will deepen your skills and knowledge in an area related to your major or a different one to become a more well-rounded thinker. 

As you develop more specific interests you will have the opportunity to work with a faulty member doing independent reading. EAS-X 399 Readings for Honors is a popular choice for majors. This course provides time for intensive study of a topic of your choice. Talk with your academic advisor or your instructors about this option.

You could also choose to work part-time with a member of the Earth and Atmospheric Sciences faculty or a faculty member from another department on a research project, either as an hourly worker or for academic credit (EAS-X 498 or EAS-E 499).

Teaching opportunities for undergraduates are available through EAS-X 371 Teaching Internship in Earth and Atmospheric Sciences.


The Earth and Atmospheric Sciences Departmental Honors Program recognizes outstanding students for their coursework and participation in research.

Recognition of departmental honors requires working on an independent research project, typically carried out under the supervision of a faculty member. This work culminates before the end of the senior year with the writing of an honors thesis. You will also be examined orally through a presentation describing your work to a committee of three faculty members.

In addition to fulfilling the requirements associated with the degree, students in the honors program have the opportunity to take special readings courses and enroll in honors sections of regular undergraduate courses.

To graduate with honors, you must maintain a minimum grade point average of 3.300. Interested students should consult the Earth and Atmospheric Sciences departmental honors advisor for details no later than first semester of your junior year.

High achieving students may be recognized for Academic Excellence in the College of Arts and Sciences, or be eligible for admission to the Hutton Honors College.

Undergraduate scholarships and awards

Students studying in the Earth and Atmospheric Sciences department may be interested in pursuing one or more of the scholarships and awards that are offered by the College of Arts and Sciences.


Internships offer you a chance to develop both technical and transferable skills while making vital professional contacts with others in the field. Many students begin exploring internship opportunities, including overseas study programs with internships, as early as their freshman year.

Learn more about internships, including the possibility of receiving credit, through The Walter Center for Career Achievement, where you’ll find many resources for both domestic and international internships.

If you secure your own internship and would like to earn credit for it, you should consider applying for ASCS-X 373 through the Walter Center for Career Achievement.
