Indeks obszaru spalonego (BAI) jest generowany na podstawie pasm czerwonego i bliskiej podczerwieni i mierzy odległość spektralną każdego piksela od referencyjnego punktu spektralnego (zmierzona odbijalność węgla drzewnego). Ten indeks ma na celu podkreślenie sygnału związanego z węglem drzewnym na zdjęciach po pożarze. Więcej informacji znajdziesz w artykule Chuvieco i in. (2002). Ten produkt jest generowany na podstawie kompozytów odbicia powierzchni MODIS/006/MYD09GA.
