AI-generated Key Takeaways
-
The FAO WaPOR dataset provides dekadal (10-day) estimates of Net Primary Production (NPP) globally at a 248.2 meter resolution.
-
NPP data, expressed in grams per square meter per day (g/m²/day), quantifies the rate of plant biomass production through photosynthesis.
-
The dataset covers the period from January 1, 2009, to March 1, 2023, and is freely available for research and non-commercial use.
-
This dataset is hosted on Google Earth Engine and can be accessed and analyzed using their platform.
-
The Food and Agriculture Organization of the United Nations (FAO) developed and maintains this dataset as part of their Water Productivity Open Access Portal (WaPOR).

Description
Net primary production (NPP) is a fundamental characteristic of an ecosystem, expressing the conversion of carbon dioxide into biomass driven by photosynthesis. The pixel value represents the mean daily NPP for that specific dekad.

The Food and Agriculture Organization of the United Nations (FAO) is mandated to collect, analyze, interpret, and disseminate information related to nutrition, food, and agriculture. In this regard, it publishes a number of databases on topics related to FAO's mandate, and encourages the use of them for scientific and research purposes. Consistent with the principles of openness and sharing envisioned under the Open Data Licensing For Statistical Databases, and consistent with the mandate of FAO, data from the Water Productivity Open Access Portal (WaPOR), as part of AQUASTAT - FAO's Global Information System on Water and Agriculture, is available free to the user community.
