מערך הנתונים הזה של בהירות כובע עם ציצית (TCB) עם נתונים חסרים נוצר על ידי החלת משוואות הכובע עם הציצית שמוגדרות ב-Lobser and Cohen (2007) על תמונות שעברו תיקון BRDF של MODIS (MCD43B4). הנתונים שהתקבלו עברו השלמה של פערים באמצעות הגישה שמתוארת במאמר של Weiss et al. (2014) כדי לבטל נתונים חסרים שנגרמו כתוצאה מגורמים כמו כיסוי עננים. לאחר מכן, הנתונים צורפו באופן זמני ומרחבי כדי ליצור את המוצר החודשי של ≈5 ק"מ.
