Biophsyical constraints on gross primary production by the terrestrial biosphere [PDF]

Biogeosciences, 2014
Persistent divergences among the predictions of complex carbon-cycle models include differences in the sign as well as the magnitude of the response of global terrestrial primary production to climate change. Such problems with current models indicate an

Underestimates of Grassland Gross Primary Production in MODIS Standard Products [PDF]

Remote Sensing, 2018
As the biggest carbon flux of terrestrial ecosystems from photosynthesis, gross primary productivity (GPP) is an important indicator in understanding the carbon cycle and biogeochemical process of terrestrial ecosystems.

Global cropland monthly gross primary production in the year 2000 [PDF]

Biogeosciences, 2014
Croplands cover about 12% of the ice-free terrestrial land surface. Compared with natural ecosystems, croplands have distinct characteristics due to anthropogenic influences.

Enhanced gross primary production and evapotranspiration in juniper-encroached grasslands. [PDF]

Global Change Biology, 2018
Woody plant encroachment (WPE) into grasslands has been occurring globally and may be accelerated by climate change in the future. This land cover change is expected to alter the carbon and water cycles, but it remains uncertain how and to what extent ...

Addressing Challenges in Simulating Inter–Annual Variability of Gross Primary Production [PDF]

Journal of Advances in Modeling Earth Systems
A long‐standing challenge in studying the global carbon cycle has been understanding the factors controlling inter–annual variation (IAV) of carbon fluxes, and improving their representations in existing biogeochemical models.

Diagnostic assessment of European gross primary production [PDF]

Global Change Biology, 2008
AbstractWe present an approach to estimate gross primary production (GPP) using a remotely sensed biophysical vegetation product (fraction of absorbed photosynthetically active radiation, FAPAR) from the European Commission Joint Research Centre (JRC) in conjunction with GPP estimates from eddy covariance measurement towers in Europe.

Maximum Gross Primary Productivity Dominates the Trend in Gross Primary Productivity in China’s Deciduous Forest Ecosystems

Forests, 2023
The terrestrial gross primary productivity (GPP) has increased over the past two decades. However, the climatic attribution and the physiological and phenological processes that control the trends in the GPP are still unclear. Here, we used remote-sensing-based vegetation GPP and phenology datasets, analyzed the spatial and temporal variation in the ...

Predicting Gross Primary Productivity in Terrestrial Ecosystems [PDF]

Ecological Applications, 1997
Our goal was to construct a simple, highly aggregated model, driven by easily available data sets, that accurately predicted terrestrial gross primary productivity (GPP; carboxylation plus oxygenation) in diverse environments and ecosystems. Our starting point was a fine-scale, multilayer model of half-hourly canopy processes that has been parametrized
