For a better understanding of how forest fires behave and interact with climate, scientists are turning to the trees. A new study out of UC Irvine shows that differences in individual tree species bet...
Forest fire is one of the most important ecological factors in the forest ecosystem. The Daxinanling forest region has not only the largest forest areas, but also the biggest forest fire burned area i...
This paper proposes a distributed intelligent system for forest fire detection based on integration of information from several distributed sensors. An automatic fire detection system with ultraviolet...
Forest fires in Northern California and Oregon were responsible for two significant regional scale aerosol transport events observed in southern British Columbia during summer 2008. A combination of g...
Forest fire is one of the most important ecological factors in the forest ecosystem. The Great Xing’an Mountain region has not only the largest forest areas, but also the biggest forest fire burned ar...
On 30 August 2009, intense forest fires in interior British Columbia (BC) coupled with winds from the east and northeast resulted in transport of a broad forest fire plume across southwestern BC. The ...
Land cover is affected by many factors including economic development, climate and natural disturbances such as wildfires. The ability to evaluate how fire regimes may alter future vegetation, and how...
This paper explores log-periodicity in a forest-fire cellular-automata model. At each time step of this model a tree is dropped on a randomly chosen site; if the site is unoccupied, the tree is plante...
During airborne in situ measurements of particle size distributions in a forest fire plume originating in Northern Canada, an accumulation mode number mean diameter of 0.34 mm was observed over Linden...
In May 2003, severe forest fires in southeast Russia resulted in smoke plumes extending widely across the Northern Hemisphere. This study combines satellite data from a variety of platforms (Moderate ...
The Chisholm forest fire that burned in Alberta, Canada, in May 2001 resulted in injection of substantial amounts of smoke into the lower stratosphere. We used the cloud-resolving plume model ATHAM (A...
Wildland fires in boreal regions have the potential to initiate deep convection, so-called pyro-convection, due to their release of sensible heat. Under favorable atmospheric conditions, large fires c...
During the ICARTT-ITOP Experiment in summer 2004 plumes from large wildfires in North America were transported to Central Europe at 3–8 km altitude above sea level (a.s.l.). These plumes were studied...
