Evaluating spectral indices and spectral mixture analysis for assessing fire severity, combustion completeness and carbon emissions

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)…

Carbon emissions and vertical pattern of canopy fuel consumption in three Pinus pinaster Ait. active crown fires in Galicia (NW Spain)

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…

Carbon credit possibilities and economic implications of fuel reduction treatments

We determined the difference in carbon (C) stocks and C emissions between treated and untreated ponderosa pine stands over 100 years on the Apache and Sitgreaves National Forests, Arizona, USA, under assumed treatment scenarios, wildfire frequency, and annual percentage of area…
