Yanmış alan indeksi (BAI), kırmızı ve yakın kızılötesi bantlardan oluşturulur ve her pikselin spektral mesafesini referans spektral noktadan (odun kömürünün ölçülen yansıtma değeri) ölçer. Bu indeks, yangın sonrası görüntülerde kömür sinyalini vurgulamak için tasarlanmıştır. Ayrıntılar için Chuvieco ve diğerleri (2002)'ne bakın. Bu ürün, MODIS/006/MOD09GA yüzey yansıtma kompozitlerinden oluşturulmuştur.
