The Atmospheric and Oceanic Sciences present the challenge of a wide variety of problems of compelling scientific interest and increasing social relevance. This is exemplified by the current concern over Planet Earth and Global Change, including issues regarding climate change, greenhouse warming, air pollution, the ozone layer, the attempts to control or modify weather phenomena, the demand for reliable longrange weather forecasts on both local and global scales, and the expanding frontiers of space science as we continue to explore the atmospheres of other planets. The department offers a broad curriculum in dynamic and synoptic meteorology, oceanography, atmospheric physics and chemistry, and upper atmosphere and space physics.
