科学家选择了陆地碳循环中的关键部分 NPP,将其视作生态系统能量流动和生态系统功能的指示器。 总初级生产力GPP(Gross Primary Production)是在一定时间内生态系统生产者获得化学能,并将其储存于生物量中的速率。 被植物所固定的能量中的部分被用于自身生长R,剩余部分的生产量就是净初级生产力NPP(Net Primary Production ) 。 目前中文互联网关于NPP的数据集的总结博客几乎没有,我这里简单总结了九种常见的NPP及GPP数据集。 主要是介绍几种覆盖全球 …
NPP Multi-Biome: Global Primary Production Data Initiative …
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.
Estimation of Global Net Primary Productivity from 1981 to 2018 …
2020年9月26日 · The global NPP has shown a significant increase trend, with an annual growth rate of 0.10 PgC/yr over the past 38 years. NPP in the northern hemisphere and southern hemisphere account for 62.0% and 38.0% of the global …
ESSD - An extended time series (2000–2018) of global NPP-VIIRS …
2021年3月5日 · In this study, we developed an auto-encoder (AE) model including convolutional neural networks to integrate DMSP-OLS NTL and NPP-VIIRS NTL data and generated an extended time series of global annual NPP-VIIRS-like NTL data from 2000 to 2018.

A global database of plant production and carbon exchange from global …
2020年10月2日 · Here, we extract data from 2,242 publications that report global change manipulative experiments and build a comprehensive global database with 5,213 pairs of samples for plant production...
Global net primary production: Combining ecology and …
1995年1月1日 · Terrestrial net primary production (NPP) is sensitive to a number of controls, including aspects of climate, topography, soils, plant and microbial characteristics, disturbance, and anthropogenic impacts. Yet, at least at the global scale, models based on very different types and numbers of parameters yield similar results.
NASA VIIRS Land Products
2024年5月17日 · Global VIIRS Gross and Net Primary Production (GPP/NPP, VNP17/VJ117) continue the global MODIS GPP/NPP data product in a consistent manner to provide 8-day and annual 500m GPP/NPP for terrestrial ecosystems. The products are provided in standard Hierarchical Data Format–Earth Observing System (HDF-EOS5) format.
HANPP Collection: Global Patterns in Net Primary Productivity (NPP)
The HANPP Collection: Global Patterns in Net Primary Productivity (NPP) maps the net amount of solar energy converted to plant organic matter through photosynthesis. NPP is measured in Units of elemental carbon and represents the primary food energy source for the world's ecosystems.
Global NPP and straw bioenergy trends for 2000–2014
2016年7月1日 · In this study we used the Biosphere Energy Transfer Hydrology (BETHY/DLR) model to compute global Net Primary Productivity (NPP) on 1 km2 resolution for the fifteen years 2000–2014. We found a global average of 60.2 Pg carbon per year, with the main contribution from the Tropics.
