Modelling the role of fires in the terrestrial carbon balance by incorporating SPITFIRE into the global vegetation model ORCHIDEE – Part 1: simulating historical global burned area and fire regimes
simulating historical global burned area fire regimes
2014/12/19
Fire is an important global ecological process that influences the distribution of biomes, with consequences for carbon, water, and energy budgets. Therefore it is impossible to appropriately model th...
Applicability of an integrated plume rise model for the dispersion from wild-land fires
rise model wild-land fires
2014/12/19
We have presented an overview of a mathematical model, BUOYANT, that was originally designed for the evaluation of the dispersion of buoyant plumes originated from major warehouse fires. The model add...
Spatial Patterns of Lightning-Ignited Forest Fires in Daxing’an Mountains, Heilongjiang Province, China, 1973-1997
Daxing'an Mountains K-Function Lightning Fire Spatial Statistics
2011/12/16
The spatial pattern of forest fire locations is of interest for fire occurrence prediction. A spatial statistical analysis of lightning-caused fires in the province of Heilongjiang, China, between 197...
Global fire emissions and the contribution of deforestation, savanna, forest, agricultural, and peat fires (1997–2009)
Global fire deforestation savanna forest agricultural peat fires
2010/12/28
New burned area datasets and top-down constraints from atmospheric concentration measurements of pyrogenic gases have decreased the large uncertainty in fire emissions estimates. However, significant ...
Fires on trees
Fires on trees math

We consider random dynamics on the edges of a uniform Cayley tree with $n$ vertices, in which edges are either inflammable, fireproof, or burt. Every inflammable edge is replaced by a fireproof edge a...
Nitrogen oxides and PAN in plumes from boreal fires during ARCTAS-B and their impact on ozone: an integrated analysis of aircraft and satellite observations
Nitrogen oxides and PAN boreal fires ARCTAS-B aircraft and satellite observations
2010/10/21
We determine enhancement ratios for NOx, PAN, and other NOy species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examine the impact of these emissions on t...
Particle size distributions from laboratory-scale biomass fires using fast response instruments
Particle size laboratory-scale biomass fires fast response instruments
2010/9/14
Particle size distribution from biomass combustion is an important parameter as it affects air quality, climate modelling and health effects. To date, particle size distributions reported from prior s...
Smoke injection heights from fires in North America: analysis of 5 years of satellite observations
Smoke injection heights fires North America
2010/2/21
We analyze an extensive record of aerosol smoke plume heights derived from observations over North America for the fire seasons of 2002 and 2004–2007 made by the Multi-angle Imaging SpectroRadiometer ...
Biomass burning aerosol emissions from vegetation fires: particle number and mass emission factors and size distributions
Biomass burning aerosol vegetation fires mass emission factors
2010/2/21
Aerosol emissions from vegetation fires have a large impact on air quality and climate. In this study, we use published experimental data and different fitting procedures to derive dynamic particle nu...
The use of NOAA/AVHRR satellite data for monitoring and assessment of forest fires and floods
