Increasing gross primary productivity under soil warming and wetting on the Tibetan Plateau

Environmental Research Letters
The soil freeze-thaw process has undergone significant changes on the Tibetan Plateau (TP) in the context of global change, resulting in the changes of soil physical and chemical properties, thereby affecting the vegetation phenology and photosynthesis ...

Gross Primary Productivity (GPP)

Seasonal median values of Gross Primary Productivity, from 2005-2020 at 30-meter spatial resolution. Data represent the spatial extent of the grasslands of Cimarron County, Oklahoma, clipped for each year using the Cropland Data Layer.

A Global, Daily Carbon Budget for Terrestrial Ecosystems Constrained by Satellite Observations of Soil Moisture: The SMAP Level 4 Carbon Product at Ten Years

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The capacity of terrestrial ecosystems to retain carbon or sequester more atmospheric carbon is frequently investigated as a potential natural climate solution. However, global carbon inventories, national carbon assessments, and atmospheric inversion studies suffer from key limitations: infrequent estimates, low spatial resolution, or a lack ...

Coupling air–water CO2 flux and primary production dynamics under hydrologic variability in a large urban estuary

Limnology and Oceanography Letters
Estuaries are critical for land‐ocean carbon exchange, but coupling mechanisms between air–sea CO2 fluxes (FCO2) and phytoplankton gross primary productivity (GPP) remain poorly understood.

Inter–Annual Variability of Model Parameters Improves Simulation of Annual Gross Primary Production

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Parametric uncertainty can hinder land surface models (LSM) from accurately simulating carbon fluxes, such as gross primary production (GPP). These models generally cannot capture inter–annual variability (IAV) of fluxes well due to missing processes, and temporally varying parameters can partially alleviate this limitation.

Decadal Water Level Decline Suppresses Ecosystem Metabolism and Mitigates Net Heterotrophy in a Floodplain Lake

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Precipitation and hydrological processes fundamentally reshape aquatic physicochemical properties and biological interactions, thereby regulating lake metabolism and carbon (C) dynamics. This study integrated 5 years of field data with machine learning to estimate 30 years of ecosystem metabolic rates (gross primary production [GPP], ecosystem

Contributions of climate change, land use change and CO2 to changes in the gross primary productivity of the Tibetan Plateau

Atmospheric and Oceanic Science Letters, 2020
The ecosystems on the Tibetan Plateau (TP) are highly vulnerable to climate change, rising CO2 concentration, and land-use and land-cover change (LULCC), but their contributions to changes in the gross primary productivity (GPP) of the TP are not clearly

A Generalized Resource‐Constrained Framework for Quantifying Ecosystem Water and Carbon Fluxes

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Gross primary productivity (GPP) and evapotranspiration (ET) represent two fundamental processes in coupled water and carbon cycles. The strong regulation of ecosystem carbon and water fluxes by stomata is well understood at the leaf level. However, the coupling is complex at regional or ecosystem scales.

Contrasting carbon cycle along tropical forest aridity gradients in West Africa and Amazonia

Nature Communications
Tropical forests cover large areas of equatorial Africa and play a substantial role in the global carbon cycle. However, there has been a lack of biometric measurements to understand the forests’ gross and net primary productivity (GPP, NPP) and their ...
