Questo set di dati sulla luminosità Tasseled Cap (TCB) con valori mancanti è stato creato applicando le equazioni Tasseled Cap definite in Lobser e Cohen (2007) alle immagini corrette BRDF MODIS (MCD43B4). I dati risultanti sono stati riempiti
utilizzando l'approccio descritto in Weiss et al. (2014) per eliminare i dati mancanti
causati da fattori come la copertura nuvolosa, quindi sono stati
aggregati temporalmente e spazialmente per produrre il prodotto mensile di circa 5 km.
Questo set di dati è stato prodotto da Harry Gibson e Daniel Weiss del
Malaria Atlas Project.
