Extreme events driving year-to-year differences in gross primary productivity across the US [PDF]

Biogeosciences, 2021
Solar-induced chlorophyll fluorescence (SIF) has previously been shown to strongly correlate with gross primary productivity (GPP); however this relationship has not yet been quantified for the recently launched TROPOspheric Monitoring Instrument ...

Higher global gross primary productivity under future climate with more advanced representations of photosynthesis

Science Advances, 2023
Gross primary productivity (GPP) is the key determinant of land carbon uptake, but its representation in terrestrial biosphere models (TBMs) does not reflect our latest physiological understanding.

Canada's Forests Are Shifting From a Recovery-Driven Carbon Sink to a Disturbance-Driven Carbon Source. [PDF]

Glob Chang Biol
Canada's terrestrial ecosystems have historically functioned as a net carbon sink but are increasingly impacted by wildfire and timber harvest. Using wall‐to‐wall, physically coherent estimates of all major carbon pools and fluxes from the Canadian Land Surface Scheme Including Biogeochemical Cycles land surface model, we show that rising wildfire ...

Modeling Global Vegetation Gross Primary Productivity, Transpiration and Hyperspectral Canopy Radiative Transfer Simultaneously Using a Next Generation Land Surface Model—CliMA Land

Journal of Advances in Modeling Earth Systems, 2023
Recent progress in satellite observations has provided unprecedented opportunities to monitor vegetation activity at global scale. However, a major challenge in fully utilizing remotely sensed data to constrain land surface models (LSMs) lies in ...

Suitability of the boreal ecosystem simulator (BEPS) model for estimating gross primary productivity in hemi-boreal upland pine forest

Metsanduslikud Uurimused, 2022
Gross Primary Productivity (GPP) is the core component of the terrestrial and global carbon cycle and Earth’s climate research. In this study, GPP estimation was performed with the Boreal Ecosystem Productivity Simulator (BEPS) model to check its ...

Impacts of Land Use Change and Atmospheric CO₂ on Gross Primary Productivity (GPP), Evaporation, and Climate in Southern Amazon

Journal of Geophysical Research: Atmospheres, 2022
AbstractRecent publications indicate that the Amazon may be acting more as a carbon source than a sink in some regions. Moreover, the Amazon is a source of moisture for other regions in the continent, and deforestation over the years may be reducing this function.

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

, 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.

Remote Estimation of Gross Primary Production (GPP) using MODIS data in Kelantan: A Preliminary Assessment

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Kelantan state is located in the north-eastern of Peninsular Malaysia, with 5.8 million hectares is covered by forested areas. Gross primary production (GPP) is the amount of carbon captured by plants and it is an important biophysical parameter in the spatio-temporal dynamics of CO2.

Distinguishing the main climatic drivers to the variability of gross primary productivity at global FLUXNET sites

Environmental Research Letters, 2023
Climate exerts both short-term and long-term impacts on the ecosystem carbon assimilation. However, the main climatic drivers for the variability of gross primary productivity (GPP) remain unclear across various timescales and vegetation types.
