After a fire in a phryganic ecosystem, the nutreint losses in above-ground plant biomass, in nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) were quantitatively different. The most important is that of nitrogen (96%), followed by magnesium (59%),…

Wildfires generate substantial emissions of nitrogen oxides (NOx) and volatile organic compounds (VOCs). As such, wildfires contribute to elevated ozone (O3) in the atmosphere. However, there is a large amount of variability in the emissions of O3 precursors and the amount of O3…

Logging slash on 73 clearcuts in the western larch/Douglas-fir forest of western Montana was broadcast burned over a wide range of environmental conditions. A broad array of fire intensities and effects was achieved. A severe wildfire was also evaluated and compared to the…

The possibility of applying infrared imagery to the study of a large, hot plume materialized by carbon particles resulting from the incomplete combustion of fuel oil is investigated. In a specific case (the PROSERPINE experiment), due to the high carbon particle content, the…

The relative contributions of double counting of carbon emissions between forest-to-nonforest cover change (FNCC) and forest wildfires are an unknown in estimating net forest carbon exchanges at large scales. This study employed land-cover change maps and forest fire data in the…

We used a Landsat Thematic Mapper (TM) image from the 2011 Wallow fire in Arizona, USA, in combination with field data to assess different methods for determining fire severity. These include the normalised burn ratio (NBR), the differenced NBR (dNBR), the relative dNBR (RdNBR)…

Accurate estimation of the canopy fuel load that is consumed during crown fires is critical for improving our knowledge of crown fire behaviour and for quantifying emissions of carbon and other gases during this type of fire. However, there is a lack of information about the…

Experimental, free-burning wood fires larger than 5 ha were similar in convection column volume after the initial buoyant, ring-vortex rose from the ground. The fire generated strong vorticity patterns which propagated upward into the convection column. The rotation suppressed…
