Dieser Datensatz mit Tasseled Cap Brightness (TCB) wurde erstellt, indem die in Lobser und Cohen (2007) definierten Tasseled-Cap-Gleichungen auf MODIS-Bilder mit BRDF-Korrektur (MCD43B4) angewendet wurden. Die resultierenden Daten wurden mithilfe des in Weiss et al. (2014) beschriebenen Ansatzes lückenlos gefüllt, um fehlende Daten zu eliminieren, die durch Faktoren wie Wolkenbedeckung verursacht wurden. Anschließend wurden die Daten zeitlich und räumlich aggregiert, um das monatliche Produkt mit einer Auflösung von etwa 5 km zu erstellen.
Dieses Dataset wurde von Harry Gibson und Daniel Weiss vom Malaria Atlas Project erstellt.
