Satellite‐Derived Leaf Photosynthetic Capacity Data Set Improves Atmospheric Inversion of Terrestrial Carbon Fluxes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurately estimating the terrestrial carbon sink is crucial for understanding the global carbon cycle. Here, we examine how different parameterizations of the key leaf photosynthetic capacity parameter, namely the maximum Rubisco carboxylation rate normalized to 25°C (Vcmax25), influence terrestrial carbon flux estimates within an atmospheric

An Empirical Model of Gross Primary Productivity (GPP) and Relations between GPP and Its Driving Factors, Biogenic Volatile Organic Compounds in a Subtropical Conifer Plantation in China

Atmosphere, 2023
Measurements of net ecosystem exchange (NEE), solar global radiation, photosynthetically active radiation (PAR) and meteorological parameters were carried out on a subtropical conifer plantation in China from 2013 to 2016. These observations were used to develop and evaluate an empirical model of gross primary production (GPP) (EMGPP) with 3-factor and

Debris Flows Suppressed Riverine Productivity and Respiration Following High‐Severity Wildfire on the Klamath River, California

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Wildfires alter terrestrial material and energy inputs to rivers, but impacts to ecosystem metabolism and dissolved oxygen (DO) are not well known due to few river ecosystem response studies during and after wildfires. In summer 2022, wildfire and heavy rains triggered debris flows into the Klamath River, where we compared immediate (days) and

Bioclimatic Reorganization of Carbon–Water–Energy Coupling Revealed by Eddy Covariance and Interpretable Machine Learning

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Ecosystem carbon, water, and energy exchange reorganize systematically along climatic gradients from humid to dry conditions. Tapering shapes indicate shifts in the relative importance of environmental drivers and ecosystem fluxes across climate space, with thicker ends representing greater influence or magnitude.

Estimation of crop gross primary production (GPP): II. Do scaled MODIS vegetation indices improve performance? [PDF]

Agricultural and Forest Meteorology, 2015
Abstract Satellite remote sensing estimates of gross primary production (GPP) have routinely been made using spectral vegetation indices (VIs) over the past two decades. The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), the green band Wide Dynamic Range Vegetation Index (WDRVIgreen), and the green band ...

Climate Controls on Carbon Dioxide Fluxes in a High‐Elevation Grassland

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Climate change is significantly influencing high‐elevation grasslands, possibly unbalancing CO2 exchanges and the sink‐source dynamics. Cumulated heat available for plant growth and vegetation cover were identified as the main controllers of phenological development and, via direct or mediated effects, of CO2 fluxes (ER and GPP).

Vegetation Productivity Slowdown on the Tibetan Plateau Around the Late 1990s

Geophysical Research Letters
Tibetan Plateau (TP) has experienced a slowdown of the vegetation greening since the late 1990s. This structural change (i.e., greening) along with canopy physiology (i.e., potential photosynthetic productivity) regulates vegetation gross primary ...

Impacts of Climate Change, Human Activities, and Their Interactions on China’s Gross Primary Productivity

Remote Sensing
Gross Primary Productivity (GPP) plays a vital role in the terrestrial carbon cycle and ecosystem functioning. Understanding its spatio-temporal dynamics and driving mechanisms is critical for predicting ecosystem responses to climate change. China’s GPP
