MYD08_M3 V6.1 הוא מוצר גלובלי של האטמוספירה שמכיל ערכים ממוצעים של פרמטרים אטמוספריים ברשת של מעלה אחת על מעלה אחת, מדי חודש.
הפרמטרים האלה קשורים למאפיינים של חלקיקי אירוסול באטמוספירה, לעומס הכולל של אוזון, לאדי מים באטמוספירה, למאפיינים אופטיים ופיזיקליים של עננים ולמדדי יציבות באטמוספירה. המוצר
מספק גם ממוצעים, סטיות תקן, נתונים סטטיסטיים משוקללים של בקרת איכות,
התפלגויות לוג-נורמליות, הערכות של אי-ודאות ונתונים סטטיסטיים
לשברירי פיקסלים שעומדים בתנאי מסוים. בהמשך מופיעה קבוצת משנה של הפסים. לרשימה מלאה אפשר לעיין ברשימת הפסים של MOD08.
