2013年8月29日 · The EMDI review and analyses produced NPP, climate, NDVI, land cover, vegetation, and soil data for a sub-set of GPPDI data: 81 Class A sites, 933 Class B sites, and 3,855 Class C 0.5-degree cell grids. Class A sites represent well-documented study sites that have complete above- and below-ground NPP measurements.

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.

2018年6月17日 · NPP is the amount of useable energy available for heterotrophs in the food web. This is basically an energy "budget" that gets "spent" on the respiration of various organisms until all the energy runs out. Most energy is spent immediately by an organism, while some goes into "savings" in the form of body weight or offspring.

This data set provides four data files containing gridded (0.5-degree) estimates of net primary productivity (NPP), elevation, temperature, precipitation, NDVI, and biome type for selected terrestrial regions of the world.

2006年6月15日 · This paper will present NPP/GPP validation results from the complete set of BigFoot sites. Biome types include boreal forest, temperate coniferous forest, temperate hardwood forest, and tropical moist forest, as well as arctic tundra, temperate grassland, desert grassland, and agricultural fields.

2 天之前 · Based on the Biome-BGC model with localized parameters, this study simulated the dynamic changes in GPP and NPP of the forests in the Ganjiang River Basin at the regional scale from 1970 to 2021 and explored the productivity of different forest vegetations and their spatio-temporal distribution characteristics at different time scales (annual ...

2014年7月20日 · 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 in...

2016年4月28日 · Despite the importance of net primary productivity (NPP) and net biome productivity (NBP), estimates of NPP and NBP for China are highly uncertain. To investigate the main sources of uncertainty, we synthesized model estimates of NPP and NBP for China from published literature and the Multi-scale Synthesis and Terrestrial Model Intercomparison ...

2015年2月1日 · We analyzed NPP responses in forest, grassland, agricultural and desert biomes to climate change, by combining the simulated data with meteorological data.

Distribution of 53 NPP sites, circle grasslands, triangle boreal forest, box tropical forest. The NPP data collection contains field measurements of biomass, estimated NPP, and climate data for terrestrial grassland, tropical forest, temperate forest, boreal forest, and tundra sites worldwide.
