By incorporating seasonal variability of herbaceous cover and biomass in the Southwest U.S., fine fuel loading can be measured. The measurements are then used to capture changes to fire behavior fuel models based on the current fire season.
The LANDFIRE program produces annual fire disturbance maps for the conterminous U.S. Recently, the program developed an image tiling and compositing process to aid in vegetation change mapping.
Forest resource managers, natural resource policy makers, and global change scientists need comprehensive, consistent, and up-to-date information on trends in forest cover and condition. This information is essential for understanding carbon [...]
Landsat 8 imagery is being used to identify increased wildfire susceptibility due to the invasion of cheatgrass on rangelands.
LANDFIRE National used approximately 5,340 Landsat scenes to map CONUS, Alaska and Hawaii. Landfire continues to rely on Landsat imagery for updates. There were 13,185 scenes processed from 1984-2009 to capture landscape change for CONUS for the [...]
Lighting ignited the Castle Rocks fire in the deep backcountry of Denali National Park and Preserve in early July, 2013. Over the next two months, the Castle Rocks fire would fluctuate between periods of activity and inactivity depending on [...]
Although dousing the flames was foremost in people’s minds during the recent Rim Fire in Stanislaus National Forest and Yosemite National Park, U.S. Geological Survey scientific work continues well after the fire is out. USGS scientists are [...]
Speeding around the Earth at 16,800 mph (27,000 kph), two Landsat satellites are quietly, expertly watching and recording changes in Earth’s lands from space. They are gathering data for people to make maps–all kinds of wonderful maps–of our [...]
Two recent images from the Landsat 8 satellite compare land conditions in the vicinity of Yosemite National Park before and during the Rim Fire. The images, from August 15 before the fire began and from August 31, can be contrasted and [...]
The Wallow Fire burned over 500,000 acres, making it the largest fire in Arizona history, to date. It is one of many large fires that fire managers and researchers have seen scorch forests nationwide since the early 2000s.
While the 138,000-acre Silver Fire still smoldered, forest restoration specialists were on the job. They analyzed maps created using Landsat satellite data to determine where the burn destroyed vegetation and exposed soil—and where to focus [...]
The Black Forest wildfire this June was one of the most destructive in Colorado history, in terms of homes lost. It started close to houses and quickly spread through the ponderosa pine canopies on the rolling hills near Colorado Springs. The [...]
In June, air pollution over Singapore and Malaysia spiked as forests in neighboring Sumatra (Indonesia) burned. Using NASA's daily fire alerts and official national maps, the fires were located in the vicinity of oil palm and acacia tree [...]
Images from Landsat satellites provided free to the public by the Department of the Interior's U.S. Geological Survey were the starting points for “a new breakthrough” reported today by Time and announced on the Official Google Blog. Using its [...]
Scientists using NASA satellite data and climate models have projected drier conditions likely will cause increased fire activity across the United States in coming decades. Other findings about U.S. wildfires, including their amount of carbon [...]
A combination of lightning, drought and human activity caused fires to scorch more than one-third of Yellowstone National Park in the summer of 1988. Within a year, burn scars cast a sharp outline on the 793,880 acres affected by fire, [...]
Kirtland's warblers are an endangered species of lightweight little birds with bright yellow-bellies that summer in North America and winter in the Bahamas. But be it their winter or their summer home, a new study using data from NASA-built [...]
Contributor: Melissa Quijada, NASA Goddard Space Flight Center NASA satellite images regularly map active fires around the world. Once a fire is out, satellite data and maps are also used by scientists to measure and protect the scorched land, [...]
Contributor: Rob Gutro, NASA Goddard Space Flight Center The largest fire in the history of the state of Arizona continues to burn and emergency managers and responders are using satellite data from a variety of instruments to plan their [...]
Source: Jan Nelson, USGS / Rob Gutro, NASA Goddard Space Flight Center The second largest fire in Arizona history, the Wallow Fire is graphically depicted by this Landsat image, taken June 7, which shows burning in the mountains of eastern [...]
Contributors: Janet L. Anderson, NASA Marshall Space Flight Center In the last few years, fire incidence in Guatemala has increased, damaging and transforming wild areas into degraded forests, savannas and sterile lands. Atrocious events have [...]
If your summer travels have taken you across the Rocky Mountains, you've probably seen large swaths of reddish trees dotting otherwise green forests. While it may look like autumn has come early to the mountains, evergreen trees don't change [...]
Source: USGS Approximately 6,000 acres of burned area is visible from space. On February 11, the U.S. Geological Survey's satellite, Landsat 7, captured an image of the fires south of Richmond and Petersburg, Virginia. The blue area near the [...]
Science brief summary by: Laura E. P. Rocchio A group of European researchers have used Landsat data collected over a quarter of a century to evaluate fire management methods in Eastern Spain. Just 40 miles southwest of the Spanish city of [...]
