Il Burn Area Index (BAI) viene generato dalle bande del rosso e del
vicino infrarosso e misura la distanza spettrale di ogni pixel da un
punto spettrale di riferimento (la riflettanza misurata del carbone). Questo
indice ha lo scopo di enfatizzare il segnale del carbone nelle immagini
post-incendio. Per maggiori dettagli, consulta
Chuvieco et al. (2002). Questo prodotto è generato dai compositi di riflettanza di superficie MODIS/006/MYD09GA.
