Validation of the Operational Meris FAPAR Products

, 2007
This paper discusses the validation of the operational Medium Resolution Imaging Spectrometer (MERIS) land product which corresponds to the biophysical variable of the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR). The FAPAR value acts

Fluorescence Quantum Efficiency Data for Europe 2018–2025

Geoscience 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 ...

An RTM-Driven Machine Learning Approach for Estimating High-Resolution FAPAR From LANDSAT 5/7/8/9 Surface Reflectance

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Fraction of absorbed photosynthetically active radiation (FAPAR) is an essential indicator of vegetation productivity and carbon uptake. Although coarse-resolution FAPAR products from moderate-resolution imaging spectroradiometer (MODIS) and visible ...

The Future of Forest Microclimate in Southeast Asia

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Forest microclimates regulate biodiversity, ecosystem functioning, and species' thermal tolerance, yet tropical forest disturbances (logging, fire and fragmentation) increasingly disrupt these conditions. Southeast Asia, home to 15% of the world's tropical forests, faces rapid deforestation and degradation, but large‐scale changes in maximum ...

Characterisation of Functional-Trait Dynamics at High Spatial Resolution in a Mediterranean Forest from Sentinel-2 and Ground-Truth Data

Remote Sensing, 2018
The characterisation of functional-trait dynamics of vegetation from remotely sensed data complements the structural characterisation of ecosystems. In this study we characterised for the first time the spatial heterogeneity of the intra-annual dynamics ...

Assessing uncertainties of in situ FAPAR measurements across different forest ecosystems [PDF]

, 2020
Carbon balances are important for understanding global climate change. Assessing such balances on a local scale depends on accurate measurements of material flows to calculate the productivity of the ecosystem.
