Global Analysis of the Relationship between Reconstructed Solar-Induced Chlorophyll Fluorescence (SIF) and Gross Primary Production (GPP) [PDF]

open access: yesRemote Sensing, 2021
Solar-induced chlorophyll fluorescence (SIF) is increasingly known as an effective proxy for plant photosynthesis, and therefore, has great potential in monitoring gross primary production (GPP). However, the relationship between SIF and GPP remains highly uncertain across space and time.

Estimation of crop gross primary production (GPP): fAPARchl versus MOD15A2 FPAR [PDF]

open access: yesRemote Sensing of Environment, 2014
Photosynthesis (PSN) is a pigment level process in which antenna pigments (predominately chlorophylls) in chloroplasts absorb photosynthetically active radiation (PAR) for the photochemical process. PAR absorbed by foliar non-photosynthetic components is not used for PSN.

Understanding drivers of aquatic ecosystem metabolism in freshwater subtropical ridge and slough wetlands

open access: yesEcosphere, 2021
How climate and habitat drive variation in aquatic metabolism in wetlands remains uncertain. To quantify differences in seasonal aquatic metabolism among wetlands, we estimated aquatic ecosystem metabolism (gross primary productivity, GPP; ecosystem ...

Impacts of Precipitation Variability on Carbon Flux Dynamics of Global Semi-Arid Savannas. [PDF]

open access: yesGlob Chang Biol
Semi‐arid ecosystems contribute most to the variability of the land carbon sink. They are water‐limited and therefore increased precipitation variability due to climate change has strong effects on their carbon cycle. We investigate the effects of precipitation amount, frequency, intensity and dry spell length on carbon fluxes of global semi‐arid ...

A Comparison of OCO-2 SIF, MODIS GPP, and GOSIF Data from Gross Primary Production (GPP) Estimation and Seasonal Cycles in North America [PDF]

open access: yesRemote Sensing, 2020
Remotely sensed products are of great significance to estimating global gross primary production (GPP), which helps to provide insight into climate change and the carbon cycle. Nowadays, there are three types of emerging remotely sensed products that can be used to estimate GPP, namely, MODIS GPP (Moderate Resolution Imaging Spectroradiometer GPP ...

Remote sensing of sun‐induced fluorescence to improve modeling of diurnal courses of gross primary production (GPP) [PDF]

open access: yesGlobal Change Biology, 2009
AbstractTerrestrial gross primary production (GPP) is an important parameter to explore and quantify carbon fixation by plant ecosystems at various scales. Remote sensing (RS) offers a unique possibility to investigate GPP in a spatially explicit fashion; however, budgeting of terrestrial carbon cycles based on this approach still remains uncertain. To
