About the Role

Great Internship opportunity for undergraduate students only. The NSF National Center for Atmospheric Research (NCAR) Education, Engagement and Early Career Development (EdEC) seeks undergraduate Earth system science students to intern in the 2027 NSF NCAR Earth System Science Internship (NESSI). The 2027 NESSI program runs for 11 weeks, from May 17 to July 30, 2027. Interns work with NSF NCAR scientists to conduct research across NSF NCAR labs on a wide range of topics, including atmospheric science, computational science, engineering, and solar & space physics. Beyond core geosciences, NSF NCAR has a strong interdisciplinary mission to bring other fields to bear on substantial problems in climate, weather, and related disciplines. Thus, there is also significant opportunity for projects in data science, social science, and science education. Research projects will be defined by student interest and the ability to pair the student with a mentor working in a similar field or topic.
