“…The choice of the sapphire window was motivated by its spectral transmittance, which is between 0.2 and 5.5 lm. Parent et al [35] and Boulet et al [36] measured in the infrared the spectral flux emitted by fires from vegetative fuels with FTIR spectroscopy. The measurements clearly exhibited that the main part of the radiation emitted by the fire was between 2 and 5.5 lm, what is included in the spectral transmittance of the sapphire window.…”

“…However, the heat flux wavelength distribution from the FPA is different from the one generated by wildland fuel flames [20] and [21]. There is comparison in literature about flammability tests conducted in the FPA and the Cone calorimeter (Cone).…”

“…The Cone heating element mainly operates at a wavelength above 2.0 µm whereas the infrared lamps of the FPA mainly operate below 2.0 µm [21]. The material tested is another part of the equation: wavelength dependent reflectance and transmittance are inducing different burning behaviors in the two apparatuses for wood and clear PMMA [20]. In-depth radiation is important in this work since the pine needle samples have a high porosity.…”

Pine needle litters, a key fuel in coniferous forest systems, are highly porous fuel beds. They provide a source of continuous fuel medium that can be easily ignited and will sustain flame spread on the ground during forest fires. This work represents an experimental study that is focused on the influence of the fuel moisture content on the burning dynamics and the flammability characteristics of forest fuel beds. The FM Global Fire Propagation Apparatus was utilized to obtain time to ignition, heat release rate, total heat released and CO/CO 2 concentration data. The methodologies applied in previous studies were improved with new modifications. The results were analyzed with respect to the sample's fuel moisture content as well as other test conditions, such as airflow condition (wind), sample holder openness and external heat flux. The importance of the fuel moisture content is critical to understand as the majority of fuels present in the natural environment have elevated moisture content compared to dead dry fuel. Samples studied are representative of wet ground fuels as well as live fuels which do burn when crowning conditions develop. The results presented here are a building block for developing an experimental database that can be used to understand the influence of environmental conditions on the flammability of porous forest fuels and assess the risks that comes with a wildfire. Furthermore, the data can also be used for fire behavior model validation.

“…The radiation from the ame consists of a continuous spectrum of soot and a discontinuous spectrum of gases primarily water vapor and CO 2 . The process spectra are primarily used to analyze ame properties such as emissivity at dierent wavelengths and to measure the temperature [2,3]. Pyrometry can be used to evaluate the temperature of luminous ames.…”

A new method for estimating the temperature of non-luminous ames is presented. The spectral radiation intensity emitted from uniform or temperature-axisymmetric CO2 gas is simulated. A new inversion scheme that utilizes intensity ratios instead of directly spectral intensities is applied. This technique eliminates the errors caused by inaccuracies in the absolute radiation intensity that result from both calibration and on-site measurement. For example, this situation can occur when a spectrometer acquires radiance within only a part of its eld of view. Neural networks are used as inverse models. The proposed inversion approach shows good results with simulated data. The analysis of example measured emission spectra from practical ames is also demonstrated.
