Smoke is more than just a byproduct of fire

The Science of Smoke Illustrated · 3:28 · Video: NASA Goddard · Watch at the source

In short: While we often view smoke as a simple byproduct of combustion, it is actually a complex mixture that fundamentally alters our planet's atmosphere. This video explores how NASA's PACE mission is decoding these particles to understand their global impact.

Smoke is composed of gases, liquids, and primarily aerosols—tiny solid or liquid particles. Because smoke is not monolithic, its behavior in the atmosphere varies significantly depending on its specific composition. By gathering detailed data on these aerosols, NASA aims to improve wildfire models and gain a clearer picture of how smoke interacts with various environmental systems.

The implications of this research extend far beyond fire management. Understanding smoke particles helps scientists predict impacts on human health, air quality, weather patterns, and cloud formation. It provides a broader perspective on the mechanics of how our planet works.
