Each year, wildfires sweep across the Western United States.
The climate crisis is expected to fuel future fires too.

In 2021, the Dixie and Bootleg fires in California and Oregon have burned more than 600,000 acres — and they’re just two of more than 90 fires raging at the beginning of August.
Now, NASA has a new way to help in the fight, using the International Space Station to track wildfires and direct firefighters to where they’re needed most.
Satellites play a major role in tracking wildfires, both for people trying to avoid the blaze and firefighters working to contain it. When you’re looking at a fire the size of Los Angeles, a bird’s eye view is the only way to get the full picture.
NASA and NOAA both track wildfires through satellites, aided by planes from the U.S. Forest Service. The strengths of one type of satellite can cover the weaknesses of another and provide a fuller picture.
Situated on the ISS, ECOSTRESS measures ground temperature on Earth. In mid-July, NASA used ECOSTRESS to track a record-breaking heatwave across the Western U.S.
Using data from ECOSTRESS, first responders can now track where a wildfire is spreading and where it’s burning most intensely.
What’s new is how it’s being put to more immediate use. Researchers at Pacific Northwest National Laboratory are incorporating ECOSTRESS data into a tracking tool for first responders.

As ECOSTRESS helps first responders direct their wildfire containment efforts, it also continues to monitor droughts, heat waves, and other markers of the climate crisis.
