There are pressing reasons for developing a better understanding of net primary production (NPP) in the world's forests. These ecosystems play a large role in the world's carbon budget, and their dynamics, which are likely to be responding to global changes in climate and atmospheric composition, have major economic implications and impacts on global biodiversity.

global terrestrial NPP, with a net loss of 22.4 Tg Carbon per year (Tg C year−1). Although small compared to total terrestrial NPP and fossil fuel carbon emissions worldwide, the urbanization-induced decrease in NPP offset 30% of the climate-driven increase (73.6 Tg C year−1) over the same period. Our findings highlight the urgent need for ...Net primary productivity (NPP) directly reflects the production capacity of vegetation and is the basis of organic material and energy cycles in the global ecosystem (Field et al. 1998; ...

VIIRS (Suomi NPP/NOAA-20) Corrected Reflectance (Bands M3, I3, M11) False Color: Red = M3 (478-498 nm), Green = I3 (1580-1640 nm), Blue = M11 (2225-2275 nm) This combination is used to map snow and ice. Snow and ice are very reflective in the visible part of the spectrum (Band M3), and very absorbent in Bands I3 and M11 (short-wave infrared, or ...Oct 08, 2018 · However comparison to our NPP stem predictions may not be straightforward because NPP stem is a poor proxy for both GPP and total NPP in the wet tropics [3,7,16], and there are very few eddy covariance time series in the tropics outside of Brazil.

    Biomass: Net primary production (NPP) is the amount of carbon fixed by plants and accumulated as biomass each year. It is a basic measure of biomass productivity. The chart shows the average NPP in the country (tC/ha/yr), compared to the global average NPP of 3-4 tonnes of carbon per year. = Global average of 3-4 tC/ha/yr

    Net primary production (NPP) is strictly defined as the difference between the energy fixed by autotrophs and their respiration, and it is most commonly equated to increments in biomass per unit of land surface and time. Because the increment in biomass over a given time depends on the rate at which new biomass is produced and also on the initial amount of carbon-assimilating photosynthetic tissue, stands with a large standing biomass often show higher NPP than stands with lower biomass.

    "NPP is right on track to ring in the New Year," said Ken Schwer, NPP project manager at NASA Goddard. "Along with VIIRS, NPP carries four more instruments that monitor the environment on Earth and the planet's climate, providing crucial information on long-term patterns to assess climate change and data used by meteorologists to improve short-term weather forecasting."These results suggest that the global N and C cycles interact strongly and that geography can mediate ecosystem response to N within certain biome types.
