Parameterization of an ecosystem light-use-efficiency model for predicting savanna GPP using MODIS EVI [PDF]
, 2014 © 2014 Elsevier Inc. Accurate estimation of carbon fluxes across space and time is of great importance for quantifying global carbon balances. Current production efficiency models for calculation of gross primary production (GPP) depend on estimates of ...

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract Occurring in 2015/16, the strong El Niño has been shown to significantly influence the pantropical carbon fluxes with multiple lines of evidence. However, a comprehensive understanding on the regional and vegetation‐specific net ecosystem productivity (NEP) in response to this El Niño event and its recovery trajectories remain unclear.

Miscellanea Geographica: Regional Studies on Development, 2014 The paper deals with the evaluation of mountain meadow vegetation condition using in-situ measurements of the fraction of Accumulated Photosynthetically Active Radiation (fAPAR) and Leaf Area Index (LAI). The study analyses the relationship between these

Fodder Biomass Monitoring in Sahelian Rangelands Using Phenological Metrics from FAPAR Time Series [PDF]
Remote Sensing, 2015 Timely monitoring of plant biomass is critical for the management of forage resources in Sahelian rangelands. The estimation of annual biomass production in the Sahel is based on a simple relationship between satellite annual Normalized Difference Vegetation Index (NDVI) and in situ biomass data. This study proposes a new methodology using multi-linear

Towards operational remote sensing of forest carbon balance across Northern Europe [PDF]
, 2007 Monthly averages of ecosystem respiration (ER), gross primary production (GPP) and net ecosystem exchange (NEE) over Scandinavian forest sites were estimated using regression models driven by air temperature (AT), absorbed photosynthetically active ...

Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1473-1488, July 2025.Abstract Vegetation phenology studies the periodic recurrence of plant life‐cycle events and is essential for understanding ecosystem responses to environmental changes. Remote sensing has become a key tool for monitoring phenological events on large spatial and temporal scales, primarily using vegetation indices like the Normalized Difference ...

Quantifying the missing link between forest albedo and productivity in the boreal zone [PDF]
Biogeosciences, 2016 Albedo and fraction of absorbed photosynthetically active radiation (FAPAR) determine the shortwave radiation balance and productivity of forests. Currently, the physical link between forest albedo and productivity is poorly understood, yet it is crucial

Continental Scale Soil Monitoring: A Proposed Multi‐Scale Framing of Soil Quality
European Journal of Soil Science, Volume 76, Issue 4, July–August 2025.ABSTRACT Globally, soils are subjected to various management practices and stressors which can lead to degradation. This makes their protection essential for sustaining many functions and services as well as maintaining the overall life support system of Earth.
