L'indice de surface brûlée (BAI) est généré à partir des bandes rouge et proche infrarouge. Il mesure la distance spectrale de chaque pixel par rapport à un point spectral de référence (la réflectance mesurée du charbon de bois). Cet indice vise à mettre en évidence le signal de charbon de bois dans les images post-incendie. Pour en savoir plus, consultez Chuvieco et al. (2002). Ce produit est généré à partir des composites de réflectance de surface MODIS/006/MCD43A4.
