Do we (need to) care about canopy radiation schemes in DGVMs? Caveats and potential impacts [PDF]

open access: yes, 2014
Dynamic global vegetation models (DGVMs) are an essential part of current state-of-the-art Earth system models. In recent years, the complexity of DGVMs has increased by incorporating new important processes like, e.g., nutrient cycling and land cover ...

Consistent assimilation of MERIS FAPAR and atmospheric CO2 into a terrestrial vegetation model and interactive mission benefit analysis [PDF]

open access: yes, 2012
The terrestrial biosphere is currently a strong sink for anthropogenic CO2 emissions. Through the radiative properties of CO2, the strength of this sink has a direct influence on the radiative budget of the global climate system.

Global mapping of potential natural vegetation: an assessment of machine learning algorithms for estimating land potential [PDF]

open access: yes, 2018
Potential natural vegetation (PNV) is the vegetation cover in equilibrium with climate, that would exist at a given location if not impacted by human activities.

Inconsistencies of interannual variability and trends in long-term satellite leaf area index products [PDF]

open access: yes, 2017
Understanding the long-term performance of global satellite leaf area index (LAI) products is important for global change research. However, few effort has been devoted to evaluating the long-term time-series consistencies of LAI products.

Analysis of the relationship between yield in cereals and remotely sensed fAPAR in the framework of monitoring drought impacts in Europe

open access: yesNatural Hazards and Earth System Sciences, 2022
. This study focuses on the relationship between satellite-measured fraction of absorbed photosynthetically active radiation (fAPAR) and crop yield cereals in Europe. Different features of the relationship between annual yield and multiple time series of

Fluorescence Quantum Efficiency Data for Europe 2018–2025

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
We present a new dataset of fluorescence quantum efficiency (ΦF) across Europe and northern Africa (2018–2025). Derived from TROPOMI SIF and MODIS PAR at 0.05° resolution, the dataset provides daily, decadal and monthly coverage. The dataset includes input bands and quality layers, enabling applications in vegetation stress monitoring and drought ...

Combining ecosystem modelling and remote-sensing to establish the spatial and temporal dynamics of the carbon budget of fast-growing tropical Eucalyptus plantations [PDF]

open access: yes, 2009
In the aim of estimating regional-scale carbon budgets of Eucalyptus plantations, the G'Day ecosystem model was combined with remotely-sensed estimates of the daily fraction of absorbed photosynthetically active radiation (fAPAR).
