Structure & Dynamics of the Atmosphere

Atmospheric scientists study the atmosphere's physical characteristics, motions, and processes, and the way in which these factors affect the rest of our environment. Knowledge of the atmosphere, its chemistry, structure and behavior is becoming increasingly relevant to the development of a safe and secure society.
