Cet ensemble de données sur la luminosité Tasseled Cap (TCB) avec des valeurs manquantes a été créé en appliquant les équations Tasseled Cap définies dans Lobser et Cohen (2007) aux images MODIS corrigées par BRDF (MCD43B4). Les données obtenues ont été complétées à l'aide de l'approche décrite dans Weiss et al. (2014) pour éliminer les données manquantes causées par des facteurs tels que la couverture nuageuse. Elles ont ensuite été agrégées de manière temporelle et spatiale pour produire le produit mensuel ≈5 km.
Cet ensemble de données a été produit par Harry Gibson et Daniel Weiss du Malaria Atlas Project.
