Understanding Trace Gases in Earth's Atmosphere

Explore the global atmospheric H2 budget, variations in trace gas concentrations, and key natural and anthropogenic sources influencing our atmosphere. Utilize a 2-D model to analyze the complex interactions of CH4, H2, CFCs, and water vapor. Learn about notable inventors and their contributions to atmospheric science.
