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. Dopo il riempimento delle lacune, i dati sono stati troncati alle soglie di [-1, 2] per garantire valori validi.
Gli output di circa 1 km con i dati mancanti vengono poi aggregati temporalmente per produrre prodotti mensili e annuali.
