Bachelor of Science in Atmospheric Science

Students on Summer 2023, Fall 2023, or Spring 2024 requirements ATSCIBS

The B.S. in Atmospheric Science degree is designed for students who plan to pursue advanced study or professional employment in the atmospheric sciences. Atmospheric Sciences is a wide-ranging discipline that includes topics as diverse as weather forecasting, global warming, air quality, environmental impacts, the ozone hole, and the study of past, present, and future climates. It considers problems that are both scientifically challenging and critical for the welfare of modern society.
