The design of a Space-borne multispectral canopy LiDAR to estimate global carbon stock and gross primary productivity [PDF]

, 2011
Understanding the dynamics of the global carbon cycle is one of the most challenging issues for the scientific community. The ability to measure the magnitude of terrestrial carbon sinks as well as monitoring the short and long term changes is vital for ...

Understanding drivers of aquatic ecosystem metabolism in freshwater subtropical ridge and slough wetlands

Ecosphere, 2021
How climate and habitat drive variation in aquatic metabolism in wetlands remains uncertain. To quantify differences in seasonal aquatic metabolism among wetlands, we estimated aquatic ecosystem metabolism (gross primary productivity, GPP; ecosystem ...

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. Despite advances in remote sensing-based GPP modeling, spatial and temporal variations of GPP are still uncertain especially under ...

Understanding the effect of disturbance from selective felling on the carbon dynamics of a managed woodland by combining observations with model predictions [PDF]

, 2017
The response of forests and terrestrial ecosystems to disturbance is an important process in the global carbon cycle in the context of a changing climate.

Plant community traits associated with nitrogen can predict spatial variability in productivity

Ecological Indicators, 2022
At present, using plant traits to predict ecosystem functions is of great significance as trait-based ecology recasts classic ecological propositions.

Regional contribution to variability and trends of global gross primary productivity

Environmental Research Letters, 2017
Terrestrial gross primary productivity (GPP) is the largest component of the global carbon cycle and a key process for understanding land ecosystems dynamics.

Diffuse Radiation Forcing Constraints on Gross Primary Productivity and Global Terrestrial Evapotranspiration

Earth's Future, 2022
The diffuse radiation fertilization effect—the increase in plant productivity in the presence of higher diffuse radiation (K↓,d)—is an important yet understudied aspect of atmosphere‐biosphere interactions and can modify the terrestrial carbon, energy ...

Constraining uncertainty in projected gross primary production with machine learning [PDF]

Journal of Geophysical Research: Biogeosciences, 2020
<p>By absorbing about one quarter of the total anthropogenic CO<sub>2</sub> emissions, the terrestrial biosphere is an important carbon sink of Earth’s carbon cycle. A key metric of this process is the terrestrial gross primary production (GPP), which describes the biogeochemical ...

Ozone vegetation damage effects on gross primary productivity in the United States [PDF]

Atmospheric Chemistry and Physics, 2014
We apply an off-line process-based vegetation model (the Yale Interactive Terrestrial Biosphere model) to assess the impacts of ozone (O3) vegetation damage on gross primary productivity (GPP) in the United States during the past decade (1998–2007).
