The remaining fixed energy (i.e., mass of photosynthate) is referred to as net primary production (NPP). NPP = GPP - respiration [by plants] Net primary production is the rate at which all the autotrophs in an ecosystem produce net useful chemical energy.
Sep 18, 2023 · 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 NPP for that specific month.
While gross primary production (GPP) is the total influx of carbon into an ecosystem through the photosynthetic fixation of CO 2, net primary production (NPP) is this gross carbon influx ...
Oct 2, 2020 · This database compiled 11 plant production and ecosystem carbon exchange variables including net primary productivity (NPP), above- and below-ground NPP (ANPP and BNPP), total biomass,...

NPP is the net carbon gain by plants. It is the balance between the carbon gained by gross primary production (GPP – i.e., net photosynthesis measured at the ecosystem scale) and carbon released by plant mitochondrial respiration, both expressed per unit land area.
Jul 20, 2014 · Variation in terrestrial net primary production (NPP) with climate is thought to originate from a direct influence of temperature and precipitation on plant metabolism. However, variation...
Net primary productivity (NPP) estimates were compiled by the Global Primary Production Data Initiative (GPPDI). The database covers 2,523 individual sites and 5,164 half-degree grid cells and underwent extensive review under the Ecosystem Model-Data Intercomparison (EMDI) process.
