Dieses Dataset mit Tasseled Cap Wetness (TCW) 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 mit dem in Weiss et al. (2014) beschriebenen Ansatz lückenlos gemacht, um fehlende Daten zu eliminieren, die durch Faktoren wie Wolkenbedeckung verursacht wurden. Nach dem Schließen der Lücken wurden die Daten auf die Grenzwerte [–1, 2] begrenzt, um gültige Werte zu erhalten.
Die lückenhaften 8-Tages-Ausgaben mit einer Auflösung von etwa 1 km werden dann zeitlich aggregiert, um monatliche und jährliche Produkte zu erstellen.
