Este artículo tiene por objetivos: (i) presentar, (ii) probar y (iii) validar un conjunto de técnicas matemáticas para predecir el número incendios (No), la superficie incendiada (A), promedio (AM), en bases anuales a escalas regionales. Una fuente datos extensa proveniente los bosques coníferas Durango se usó ajustar (1970-2011) (2012-2016) las modelaje. La mayoría modelos probabilísticos esto...

We developed a technique for studying seasonal and interannual variation in pyrogenic carbon emissions from Africa using a modelling approach that scales burned area estimates from L3JRC, a map recently generated from remote sensing of burn scars instead of active fires. Carbon fluxes were calculated by the novel fire model SPITFIRE embedded within the dynamic vegetation model framework LPJGUES...

Wildfire cumulative frequency – area distributions of Mediterranean landscapes are examined for agreement with self-similar (fractal) behavior. Our results support landscape-specific restricted scaling regions of 1.5 – 3.5 orders of magnitude in size, which are delimited by breakpoints or ‘cut-offs’. By identifying the extent of such regions in the fractal frequency – area distribution of wildf...

Wildfire number and burned area temporal dynamics within all of Siberia and along a south-north transect in central Siberia (45 ̋–73 ̋ N) were studied based on NOAA/AVHRR (National Oceanic and Atmospheric Administration/ Advanced Very High Resolution Radiometer) and Terra/MODIS (Moderate Resolution Imaging Spectroradiometer) data and field measurements for the period 1996–2015. In addition, fire ...

Thick smoke routinely cloaks Southern California hills, highways, and neighborhoods during this region’s autumn wildfire season, with drought contributing to worse fires than usual in the past two years. Wildfire emissions generate larger aerosols than those produced by vehicles—up to 0.4 micrometers (μm) in diameter compared with less than 0.15 μm—according to a new study led by Constantinos S...

Societal safeguards, established by those who have shared perceptions of the importance of safety and taking preventative measures, reduce the incidence of accidents that harm people and damage property. These safeguards prevent or discourage community members from partaking in careless behaviors that often lead to accidents. Wildland urban interface communities that recognize the importance of...

As human impacts from wildfires mount, there is a pressing need to understand why structures are lost in destructive fires. Despite growing research on factors contributing structure loss, fewer studies have focused some fires and others not. We characterized overall differences between that resulted loss (“destructive fires”) those did not (“non-destructive wildfires”) across three California ...
