Colorado State University

What you'll study

The PhD programme combines advanced coursework, comprehensive examinations and an original research dissertation. Core topics typically include atmospheric dynamics, physical meteorology, boundary layer processes, cloud and precipitation physics, radiative transfer, and numerical weather prediction. Elective and specialised modules cover subjects such as:

• Mesoscale and synoptic meteorology
• Climate variability and climate modelling
• Atmospheric chemistry and air quality
• Remote sensing and radar meteorology
• Boundary layer meteorology and land–atmosphere interactions
• Data assimilation and high-performance computing for weather and climate
• Cloud microphysics and aerosol–cloud interactions

Programme structure normally includes advanced coursework in the first one to two years, followed by a qualifying or candidacy examination and focused research under the supervision of a faculty advisor. Students develop a dissertation that contributes new knowledge to the field and is defended before a faculty committee. Opportunities for field campaigns, instrument deployment, model development and interdisciplinary collaborations are common.

Entry requirements

Applicants are expected to hold a strong master's degree or equivalent in atmospheric sciences, meteorology, physics, applied mathematics, engineering or a closely related field. A solid foundation in calculus, differential equations, linear algebra, and statistics is essential.

• Academic transcripts demonstrating strong performance at undergraduate and graduate level.
• A statement of research interests outlining proposed areas of study and potential faculty mentors.
• Letters of recommendation from academic or professional referees who can attest to research potential.
• Evidence of quantitative and computational skills; prior research experience or publications are advantageous.
• International applicants will need to meet English language proficiency requirements as set by the university.

Admission is competitive and typically considers the research fit with faculty, the applicant's preparation and the availability of research funding or assistantships. Specific application components and any standardised test policies are set by the graduate school and department.

Career prospects

Graduates of the PhD programme pursue careers across academia, government and the private sector. Typical career paths include:

• University faculty and postdoctoral research positions focused on teaching and leading research projects.
• Research scientist roles at national laboratories and government agencies, including operational meteorology, climate services and environmental monitoring.
• Positions in meteorological services, numerical weather prediction centres and climate modelling groups.
• Industry roles in renewable energy, aviation meteorology, consulting, remote sensing companies and data science firms that require atmospheric expertise.
• Policy and applied science positions in environmental agencies, NGOs and international organisations addressing climate risk, air quality and adaptation.

The programme emphasises transferable skills such as quantitative analysis, numerical modelling, scientific programming, data assimilation and communication of research to technical and non-technical audiences.

Why study at Colorado State University

Colorado State University’s Department of Atmospheric Science has a long-established research programme with faculty working across theoretical, observational and modelling aspects of the atmosphere. The department benefits from strong collaborations with nearby research organisations and federal laboratories, a diversity of active research groups, and regular field campaigns that leverage Colorado’s varied terrain and climate.

Students have access to specialised facilities and resources, including observational platforms (radars, lidars, instrumented towers), high-performance computing resources for model development and data assimilation, and centres focused on climate, air quality and severe storms. The Fort Collins location offers proximity to plains and mountain environments favourable for mesoscale and orographic studies, while institutional partnerships expand opportunities for internships and collaborative projects.

Faculty mentorship, a research-focused curriculum and cross-disciplinary collaboration make the programme well suited for students seeking rigorous preparation for research careers addressing societally relevant atmospheric and climate challenges.
