MYD08_M3 V6.1 هو منتج عالمي للغلاف الجوي يحتوي على قيم متوسطة شهرية لشبكة 1 × 1 درجة لمعلمات الغلاف الجوي.
وتتعلّق هذه المَعلمات بخصائص جزيئات الهباء الجوي في الغلاف الجوي، وكمية الأوزون الإجمالية، وبخار الماء في الغلاف الجوي، والخصائص البصرية والفيزيائية للسحب، ومؤشرات استقرار الغلاف الجوي. يوفر المنتج أيضًا الوسائل والانحرافات المعيارية والإحصاءات المرجّحة لضمان الجودة وتوزيعات السجلّ العادي وتقديرات عدم اليقين والإحصاءات الخاصة بكسور وحدات البكسل التي تستوفي بعض الشروط. في ما يلي مجموعة فرعية من النطاقات، وللاطّلاع على القائمة الكاملة، يُرجى الرجوع إلى قائمة نطاقات MOD08.
