Vocabulary

Infrared (adjective): A type of light that can’t be seen but can detect heat.

Revolutionize (verb): To completely change something in a way that makes it much better or different.

Forecast (verb): To predict or estimate a future event.

Scientists are using high-tech tools like drones, laser scanners, and computer models to study and fight wildfires.

A new way to study fires

Wildfires are becoming more common due to hotter, drier weather. To better understand and prevent them, scientists in Utah recently conducted a massive experiment using a planned fire. It was part of a forest project designed to clear older trees and make space for young aspen trees that elk like to graze on.

High-tech fire tools

During the burn, helicopters dropped flames from the sky, while ground crews lit smaller fires. As the fire progressed, scientists collected data using cutting-edge technology. Drones flew over the fire, capturing infrared images to measure heat. Laser scanners mapped the fire’s growth, and instruments on towers measured wind speed and smoke levels.

Predicting fire and smoke

Computer models helped predict where the fire and its smoke would move. This technology could revolutionize wildfire prediction, allowing communities to receive early warnings. For example, schools could be told in advance if smoky air is heading their way, and keep students indoors.

Predicting fire and smoke

These new tools can also help firefighters. Better models mean they can forecast where wildfires will spread, making firefighting safer and more effective.
