On the relationship between FAPAR and NDVI
Remote Sensing of Environment, 1994Abstract The influence of pixel heterogeneity, background, atmospheric and bidirectional effects on the relationship between fraction of photosynthetically active radiation absorbed by the photosynthesizing tissue in a canopy (FAPAR) and normalized difference vegetation index (NDVI) is investigated using a three-dimensional model of radiation ...

Seasonality of albedo and FAPAR in a boreal forest
Agricultural and Forest Meteorology, 2017Abstract Satellite data are continuously used to monitor albedo and fraction of absorbed photosynthetically active radiation (FAPAR), which are key components in determining the energy balance and productivity of forests. However, due to the mismatch between spatial resolution of the satellite data and forest stand size, coarse resolution satellite ...

FAPAR and BRDF simulation for row crop using Monte Carlo method
2014 IEEE Geoscience and Remote Sensing Symposium, 2014Row crop is an important cultivation form in China. It is considered to be a transitional canopy structure between continuous vegetation and discrete vegetation. Lots of physical models of row crop were established to invert vegetation parameters of row crop. Monte Carlo model is a reliable reference for those physical models.

On the bias of instantaneous FAPAR estimates in open-canopy forests
Agricultural and Forest Meteorology, 2010Abstract Global products of the fraction of absorbed photosynthetically active radiation (FAPAR) are operationally available from a variety of space agencies. A proper validation of these products is essential and hinges on the acquisition of accurate ground-based FAPAR estimates of the vegetation contained within the field of view of the space ...

Monitoring FAPAR over land surfaces with remote sensing data
SPIE Proceedings, 2004Temporal changes of terrestrial vegetation have traditionally been monitored using empirical remote sensing tools, which are sensitive to perturbations as well as to the spectral properties of the sensor. Advances in the understanding of radiation transfer theory, and the availability of higher performance modern instruments, have led to the ...

Estimation of LAI, fAPAR and fCover of Sahel rangelands (Gourma, Mali)
Agricultural and Forest Meteorology, 2014Abstract Leaf area index, LAI , fraction of absorbed photosynthetic active radiation, fAPAR , and vegetation cover fraction, fCover , drive the main vegetation canopy processes and are key variables in ecosystem, climate, hydrology and biogeochemistry models. The present study aims to evaluate the joint use of hemispherical photographs and the CAN-

Prototyping algorithm for retrieving FAPAR using MSG data in the context of the LSA SAF project
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007This paper describes the prototyping algorithm developed for retrieving the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) using MSG data in the framework of satellite application facility on land surface analysis (LSA SAF). The prototyping relies on the Roujean and Breon (1995) method, which is based on simulations of visible and ...
