NSF NCAR Earth System Science Internship (NESSI)

Job Description Summary :

This opportunity is open ONLY to undergraduates enrolled in a degree-seeking program at a U.S. university or college.

The NESSI program cannot accommodate students who are attending schools on a quarterly schedule.

The NSF National Center for Atmospheric Research (NCAR) Education, Engagement, and Early Career Development (EdEC) seeks undergraduate Earth System Science students to participate as interns in the 2026 NSF NCAR Earth System Science Internship (NESSI).

The 2026 NESSI will run for 11 weeks, from May 18 - July 31, 2026.

Interns collaborate with NSF NCAR scientists and engineers on research across any NSF NCAR laboratories, exploring a wide range of topics in Earth system science, such as atmospheric science, computational science, engineering, and solar and space physics.

Beyond the core geosciences, NSF NCAR's interdisciplinary mission encourages the integration of various fields to address complex challenges in climate, weather, and related Earth system disciplines.

As a result, there are also valuable opportunities for projects in data science, social science, and science education. Each research project is shaped by the student's interests and the availability of an NSF NCAR mentor working in a related field or topic.

What You Will Do

Here is a brief summary of what one would expect to be generally responsible for in this role.

Key Responsibilities :

Research : Interns work with NSF NCAR scientists to conduct research in any NSF NCAR lab(s) on a wide range of topics, including atmospheric science, computational science, engineering, and solar & space physics. In addition to research in core geosciences, NSF NCAR has a strong interdisciplinary mission to apply knowledge from other fields to address significant issues in climate, weather, and related disciplines. Thus, there is also a significant opportunity for data science, social science, and science education projects. Research projects should be defined by the student's interest and the ability to pair them with a mentor working in a similar field or topic.

Reports and Presentations : At the conclusion of the summer program, each intern prepares an oral and poster presentation of their work to be presented either in person or virtually to scientists, staff, and peers.

Community and Professional Behavior : NESSI interns work together and are part of a larger community of UCAR and NSF NCAR summer interns. NESSI interns will conduct themselves in an appropriate and professional manner, adhering to UCAR's Code of Conduct. Interns are expected to participate during regular office hours, when NESSI functions fully, and while traveling for the internship.
