Forests, 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. Here, we used remote-sensing-based vegetation GPP and phenology datasets, analyzed the spatial and temporal variation in the ...

Global response of terrestrial gross primary productivity to climate extremes
Science of the Total Environment, 2021Extreme climate events undoubtedly have essential impacts on ecosystem gross primary productivity (GPP), but the global spatio-temporal patterns of GPP responses to climate extremes are unclear. In this study, we analyzed the responses of GPP to temperature and precipitation extremes during historical (1901-2016) and future (2006-2100) periods using ...

Uncertainty analysis of multiple terrestrial gross primary productivity products
Global Ecology and Biogeography, 2022AbstractAimGross primary productivity (GPP) of vegetation is an important component of the carbon balance of terrestrial ecosystems. With the development of science and technology, there has been a proliferation of multiple GPP products, yet large uncertainties exist in the global GPP estimated by different GPP products.

Simulating Gross Primary Productivity of Humid‐Temperate Pastures
Agronomy Journal, 2008Although most pasture growth models simulate many above‐ and belowground components of the plant community, calibration and validation are usually based only on periodic measurements of aboveground forage yield. This research used daily measurements of gross primary productivity (GPP) to validate the photosynthesis subroutine of the Integrated Farm ...

On validation of the MODIS gross primary production product
IEEE Transactions on Geoscience and Remote Sensing, 2006Validation can be defined as "the process of assessing by independent means the quality of the data products derived from the system outputs." Thus, it is necessary to derive alternative sources of data that correspond to the variable in question, in this case the gross primary production as generated from the Moderate Resolution Imaging Spectrometer ...

TURC: A diagnostic model of continental gross primary productivity and net primary productivity
Global Biogeochemical Cycles, 1996TURC, a diagnostic model for the estimation of continental gross primary productivity (GPP) and net primary productivity (NPP), is presented. This model uses a remotely sensed vegetation index to estimate the fraction of solar radiation absorbed by canopies, and an original parameterization of the relationship between absorbed solar radiation and GPP ...

Gross Primary Production of Terrestrial Vegetation
2013Gross primary production (GPP) of vegetation is the first and important flux of the terrestrial carbon cycle, and there is no direct measurement technique for GPP at ecosystem and landscape scales. A number of satellite-based Light Use Efficiency (LUE) models or Production Efficiency Models (PEM) have been developed to estimate GPP in the past few ...

Assimilation of satellite observations for the estimation of Savanna gross primary production
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015Monitoring vegetation gross primary production (GPP) is required for both carbon balance studies and early warning systems aiming to detect unfavorable crop and pasture conditions. This manuscript describes the assimilation of MODIS observations by a simple process model, fed by meteorological data (temperature, incident radiation and rainfall) and ...
