In view of the increasingly severe
Wildfire research and policy experts testifying at the hearing encouraged Congress to focus on improving wildfire modeling and monitoring technologies such as high-resolution satellites. They also called for developing a standardized wildfire warning scale to better alert the public to impending threats.
The hearing reflects a broader interest among policymakers in wildfire threats and mitigation technologies. That same week, President Biden announced
Lofgren said in her opening statement
“As the risk for catastrophic wildfire grows, so should our ability to forecast wildfires and to mitigate fire risk,” Lofgren added. She noted the bill would build on a provision
She also said the bill would aim to better integrate science agencies into federal wildfire response strategies.
Earlier this year, Lofgren and 46 other members of Congress petitioned
Committee Ranking Member Frank Lucas (R-OK) echoed Lofgren’s views on the importance of interagency coordination, pointing to NASA’s Earth-imaging satellites, NOAA’s incident meteorologists
“We must be certain that all the work of these agencies is carried out in a coordinated manner and is being effectively put into operation by agencies such as the Forestry Service and the Department of the Interior,” he noted.
Witnesses at the hearing identified the lack of access to observational data as a key impediment in current wildfire research and monitoring efforts.
San José State University meteorologist Craig Clements said there is a particular need for high-resolution, long-duration data sets to inform studies and modeling of fire and smoke behavior as well as the weather systems associated with wildfires. He said one result of current observational gaps is an inadequate understanding of how fire–atmosphere interactions affect wildfire spread and noted that wildfires resulting from such interactions are especially dangerous and unpredictable.
Observing that fire weather research receives less support than other types of severe storm research, Clements also argued the wildfire community needs the equivalent of the specialized aircraft NOAA uses to collect data within hurricanes. One option to achieve such a capability would be to outfit fire suppression aircraft with science instrumentation, Clements said.
Miami University geography professor Jessica McCarty outlined the limitations of current satellite-based observing systems. She noted that current spaceborne fire-detection systems often rely on polar-orbiting satellites that are overhead two-to-four times a day and have pixel resolutions between about one-third of a kilometer and one kilometer.
By contrast, she said current geostationary systems like NOAA’s GOES-R Series capture images of the Earth every five-to-15 minutes but have pixel resolutions between one-half of a kilometer and two kilometers. Meanwhile, the U.S. Geological Survey’s Landsat satellite has a resolution of 30 meters, though it is only overhead every 16 days.
McCarty said that NOAA’s next geostationary satellite constellation, called GeoXO
McCarty also suggested that applications other than wildfire tracking are often prioritized in the development of satellite platforms, which she said leads at times to suboptimal resolution for wildfire tracking. She lamented that under current plans the GeoXO satellites’ highest resolution will be one-half of a kilometer and called for the development of systems with improved spatial resolution.
Several witnesses discussed options for improving wildfire response coordination among federal agencies.
Clements argued that agencies’ research efforts generally are “not well coordinated,” but said one exception is the Joint Fire Science Program
McCarty also cited JFSP as a model of successful interagency cooperation, remarking, “We should not reinvent the wheel when a functioning and successful federal mechanism that collaborates with nonfederal partners at all levels already exists.” She noted the program funds 15 regional fire knowledge exchange networks
Erik Litzenberg, chair of the Wildland Fire Policy Committee at the International Association of Fire Chiefs, likewise called for using existing coordinating mechanisms such as JFSP and the Wildland Fire Leadership Council
Litzenberg suggested one idea ripe for interagency action is the development of a standardized wildfire warning scale similar to the Richter scale used for earthquakes and the Saffir-Simpson scale for hurricane winds. He said the proposed scale would inform emergency personnel about the level of firefighting resources required and the public about whether to shelter in place or evacuate.
“A lot of the catastrophic issues we’ve seen during fires are in the movement of people. And obviously, that is for all of us the number-one value, and the more we can communicate with people what to expect, the better our response system will be,” he said.
