Bu boşluk doldurulmuş Tasseled Cap Wetness (TCW) veri kümesi, Lobser ve Cohen (2007) tarafından tanımlanan Tasseled Cap denklemlerinin MODIS BRDF düzeltilmiş görüntülerine (MCD43B4) uygulanmasıyla oluşturulmuştur. Elde edilen veriler, bulut örtüsü gibi faktörlerden kaynaklanan eksik verileri ortadan kaldırmak için Weiss ve diğerleri (2014) tarafından belirtilen yaklaşımla doldurulmuştur. Boşluk doldurma işleminden sonra, geçerli değerler elde etmek için veriler [-1, 2] eşiklerine göre kırpıldı.
Boşlukları doldurulmuş 8 günlük ~1 km çıkışlar daha sonra aylık ve yıllık ürünler oluşturmak için zamansal olarak toplanır.
