| Abstract: | Differenced normalized burn ratio (dNBR) is a remote sensing technique measuring
forest fire burn severity – the post-fire effects on local forest ecology. Understanding how
dNBR varies across landscapes as fuel, local weather conditions, and terrain changes
provides useful insight into the possible application of dNBR as a data source for fuel
consumption and emission modeling. This study evaluated dNBR terrain trends in
nineteen forest fires in the Western conterminous United States that burned from 2000 to
2003. Terrain variables tested for possible correlation with dNBR included elevation,
slope, aspect, and annual incident solar radiation. Linear results proved significant (p <
0.05) for elevation, slope, and annual incident solar radiation but with low coefficients of
determination. Categorical analyses of variance found significant mean differences in all
severity classes for each terrain variable. Results demonstrate that terrain controls on
dNBR in these fires emerge over large scales as terrain alters local vegetation and fire
behavior trends |
