Abstract. We use a coupled atmosphere- re model to simulate a re that occurred on August 14{17, 2009, in the Harmanli region, Bulgaria.Data was obtained from GIS and satellites imagery, and from stan...
Ignition from a Fire Perimeter in a WRF Wildland Fire Model
Ignition Fire Perimeter WRF Wildland Fire Model Atmospheric and Oceanic Physics

Abstract: The current WRF-Fire model starts the fire from a given ignition point at a given time. We want to start the model from a given fire perimeter at a given time instead. However, the fuel bala...
Global fire emissions and the contribution of deforestation, savanna, forest, agricultural, and peat fires (1997–2009)
Global fire deforestation savanna forest agricultural peat fires

meteorological factors fire activity the North American boreal forest fire weather forecasting
2010/8/16
The effects of lightning and other meteorological factors on wildfire activity in the North American boreal forest are statistically analyzed during the fire seasons of 2000–2006 through an integratio...
The sensitivity of CO and aerosol transport to the temporal and vertical distribution of North American boreal fire emissions
CO aerosol transport North American boreal fire emissions

Smoke-haze episodes caused by vegetation and peat fires affect parts of Indonesia every year with significant impacts on human health and climate. Particularly fires in degenerated peat areas release ...
Around the world in 17 days - hemispheric-scale transport of forest fire smoke from Russia in May 2003
hemispheric-scale transport forest fire smoke Russia
2009/3/4
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 ...
Modeling of biomass smoke injection into the lower stratosphere by a large forest fire（Part II）: sensitivity studies
biomass smoke lower stratosphere forest fire sensitivity studies
2009/1/20
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...
We screened the algorithm 2 (308 K threshold) European Space Agency (ESA) World Fire Atlas (WFA), for the period 1997–2002, using ancillary land cover, night-lights and volcanic activity datasets, com...
