Monitoring the impact of aerosol contamination on the drought-induced decline of gross primary productivity

, 2015
Southwestern China experienced a period of severe drought from September 2009 to May 2010. It led to widespread decline in the enhanced vegetation index (EVI) and gross primary productivity (GPP) in the springtime of 2010 (March to May).

Increasing Future Global Compound Heat Flash Droughts and Socioeconomic Exposure

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Compound heat flash droughts (CHFDs) can severely impact human society. However, the spatiotemporal evolution and socioeconomic impacts under future scenarios remain poorly understood. Here, we conduct a global assessment of spatiotemporal patterns and socioeconomic exposure of CHFDs using reanalysis data (1950–2024) and future projections ...

Phenology of gross primary productivity in rivers displays high variability within years but stability across years

Limnology and Oceanography Letters
Modeling and sensor innovations in the last decade have enabled routine and continuous estimation of daily gross primary productivity (GPP) for rivers. Here, we generate and evaluate within and across year variability for 59 US rivers for which we have ...

In Situ and Space‐Based CO2 Observations Reveal Moisture‐Induced Seasonal Compensation of the Western U.S. Carbon Cycle

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Earth's arid and semi‐arid regions have been hypothesized to contribute significantly to interannual variability of the global terrestrial carbon sink. Arid and semi‐arid regions such as the Western U.S. also show high vulnerability to climate extremes in the form of droughts, heatwaves, and large forest fires, compelling a need to quantify ...

Uncertainty Analysis of Gross Primary Production (GPP) Remote-Sensing Products and Its Influencing Factors in Southwest China

Remote Sensing
Gross primary production (GPP) is a key indicator to evaluating ecosystem carbon sinks. Southwest China is characterised by diverse ecosystems and abundant forest resources and represents one of the most important carbon reservoirs in China. Therefore, a quantitative assessment of the uncertainty of existing GPP products and their influencing factors ...

Attribute parameter characterized the seasonal variation of gross primary productivity (alpha(GPP)): Spatiotemporal variation and influencing factors

, 2020
The seasonal dynamic of gross primary productivity (GPP) has influences on the annual GPP (AGPP) of the terrestrial ecosystem. However, the spatiotemporal variation of the seasonal dynamic of GPP and its effects on spatial and temporal variations of AGPP

History Matching of Soil Moisture and Evapotranspiration Over Europe Using Iterative Ensemble Smoothers

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Land surface models are crucial components within earth system models, simulating the exchanges of water, energy, carbon, and nitrogen between the land surface, atmosphere, and subsurface. One challenge is the large number of uncertain parameters in these models.

Loss and recovery of vegetation productivity in response to extreme drought during 2022 across China

Ecological Indicators
Extreme droughts can severely impact terrestrial vegetation productivity. In the summer of 2022, approximately 32.7% of China’s land area experienced extreme drought conditions, marked by reduced rainfall both in terms of amount and intensity, prolonged ...

Gross Primary Productivity

, 2018
Spatio-temporal distribution of per-pixel Gross Primary Productivity (GPP) was modeled using GPP from the eddy covariance CO2 flux tower measurements and MODIS 8–day 500m surface reflectance derived Green Biomass (GBM) composites.
