MYD17A3HGF V6.1 प्रॉडक्ट, 500 मीटर पिक्सल रिज़ॉल्यूशन पर सालाना सकल और शुद्ध प्राथमिक उत्पादकता (जीपीपी और एनपीपी) के बारे में जानकारी देता है. साल भर का एनपीपी, दिए गए साल के सभी आठ दिनों के नेट फ़ोटोसिंथिसिस(पीएसएन) प्रॉडक्ट (MYD17A2H) के योग से मिलता है. पीएसएन वैल्यू, कुल प्राइमरी प्रॉडक्टिविटी (जीपीपी) और रखरखाव के लिए श्वसन (एमआर) के बीच का अंतर है (जीपीपी-एमआर).
