NASA Studies How COVID-19 Shutdowns Affect Emissions

The video tutorial explores how atmospheric models, like NASA's Geos model, help us understand the movement of chemicals and air quality changes. It highlights the impact of the 2020 pandemic on global emissions, particularly nitrogen dioxide, due to reduced human activity. The tutorial explains how models predicted emissions without shutdowns and compared them to real-world data, revealing significant reductions. This analysis provides insights into the relationship between human activities and air pollution, emphasizing the need for combining surface observations, satellite data, and computer models to fully understand air quality.
