(NASA) ECOSystem Spaceborne Thermal Radiometer Experiment Report: ECOSTRESS measures surface temperature from the vantage point of the ISS and its ability to observe fires of the Northwest US often twice per day at a high spatial resolution (around 70 meters) makes it ideal for tracking fires #AceNewsDesk report

#AceNewsReport – Aug.03: As of July 28, 2021, the size of the Bootleg Fire in southern Oregon was more than 410,000 acres, making it the largest wildfire currently burning in the U.S.

#AceDailyNews reports that ECOSTRESS Data Incorporated Into New Wildfire Response Tool using NASA’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) is aiding in the fight against fires in the Western U.S………So far, some 400 buildings and more than 340 vehicles have been destroyed. Wildfire responders have managed to contain about 53% of the fire, and new data from ECOSTRESS is helping.

NASA’s ECOSTRESS instrument captured ground-surface temperature data over southern Oregon’s Bootleg Fire

The instrument on the International Space Station is uniquely positioned to provide wildfire responders with a high-resolution look at fire progression. 

Researchers on the RADR-Fire team at Pacific Northwest National Laboratory have been experimenting with ECOSTRESS data as part of a new tool now being implemented for first responders like the U.S. Forest Service.

In the above visualization, ECOSTRESS is tracking the movement of the Bootleg Fire and identifying its proximity to critical infrastructure — areas in red represent the hottest pixels ECOSTRESS detected. The extreme heat in those areas indicates the fire front, or where resources are most needed.

The capabilities of ECOSTRESS are unique. Satellites that acquire data more frequently don’t have high-enough resolution to track the fine line of the fire front, and satellites with higher resolution than ECOSTRESS cross over the same area much less frequently (every 5 to 16 days).

Dixie Fire

ECOSTRESS also captured data over Northern California’s Dixie Fire, which has doubled in size to more than 220,000 acres over the last few days. In the Dixie Fire data visualization above, the red areas show the hottest pixels – and fire movement – from July 15 to July 24. The most heavily affected areas are south of Lake Almanor in Plumas County. As of July 27, the Dixie Fire was 23% contained.

More than 7,000 personnel are involved in the wildfire response to the two fires. Although they have many tools in their arsenal, the use of spaceborne data like that provided by ECOSTRESS is still relatively new – and also serves as a good example of the versatility and real-world impact satellite data can provide.
