Comparing global models of terrestrial net primary productivity (NPP): overview and key results

Global Change Biology, 1999
SummarySeventeen global models of terrestrial biogeochemistry were compared with respect to annual and seasonal fluxes of net primary productivity (NPP) for the land biosphere. The comparison, sponsored by IGBP‐GAIM/DIS/GCTE, used standardized input variables wherever possible and was carried out through two international workshops and over the ...

Impact of climate change on net primary production (NPP) in south Iran

Environmental Monitoring and Assessment, 2020
Climate change is a natural hazard which threatens the sustainable development of human health, food security, economic well-being, and natural resources. It also affects photosynthesis, plant respiration, and decomposition of organic matter that contribute to atmospheric carbon flow.

Estimating Net Primary Productivity (NPP) and Debris-Fall in Forests Using Lidar Time Series

Remote Sensing, 2021
Temporal series of lidar, properly field-validated, can provide critical information allowing in-ferences about the dynamics of biomass and carbon in forest canopies. Forest canopies gain carbon through net primary production (NPP) and lose carbon through canopy component damage and death, such as fine and coarse woody debris and litterfall ...

Quantifying the contributions of climate factors and human activities to variations of net primary productivity in China from 2000 to 2020

Frontiers in Earth Science, 2023
Net primary productivity (NPP) plays a vital role in the globe carbon cycle. Quantitative assessment of the effects of climate changes and human activities on net primary productivity dynamics is vital for understanding the driving mechanisms of ...

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

Satellite-driven modelling of Net Primary Productivity (NPP): Theoretical analysis

Remote Sensing of Environment, 2009
Ecological models are central to understanding the global hydrological and carbon cycles, and need data from Earth Observation to function effectively at regional to global scales. Here, we develop and apply an end-to-end analysis that relates the requirements of ecological models to the capabilities of satellite-sensors, starting with radiometric ...

The 2010 spring drought reduced primary productivity in southwestern China [PDF]

, 2012
Many parts of the world experience frequent and severe droughts. Summer drought can significantly reduce primary productivity and carbon sequestration capacity. The impacts of spring droughts, however, have received much less attention.

Spatio-temporal patterns and dynamics of net primary productivity for Kazakhstan [PDF]

, 2013
Monitoring of net primary productivity (NPP) is especially important for the fragile ecosystems in arid and semi-arid regions. Great interest exists in observing large-scale vegetation dynamics and understanding spatial and temporal patterns of NPP in ...
