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 ...

Crop Yield Estimation in the Canadian Prairies Using Terra/MODIS-Derived Crop Metrics

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
We evaluated the utility of Terra/MODIS-derived crop metrics for yield estimation across the Canadian Prairies. This study was undertaken at the Census Agriculture Region (CAR) and the Rural Municipality (RM) of the province of Saskatchewan, in three ...

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 ...

Vegetation modulates the impact of climate extremes on gross primary production [PDF]

Biogeosciences, 2020
Abstract. Drought and heat events affect the uptake and sequestration of carbon in terrestrial ecosystems. Factors such as the duration, timing, and intensity of extreme events influence the magnitude of impacts on ecosystem processes such as gross primary production (GPP), i.e., the ecosystem uptake of CO2.

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.

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 ...

Metabolic compensation constrains the temperature dependence of gross primary production [PDF]

Ecology Letters, 2017
Abstract Gross primary production ( GPP ) is the largest flux in the carbon cycle, yet its response to global warming is highly uncertain. The temperature dependence of GPP is directly linked to photosynthetic physiology, but the ...
