Influence of small-scale structure on radiative transfer and photosynthesis in vegetation canopies

The use of Beer's law to describe the radiation regime in plant canopies is valid for a sufficiently large volume filled densely with phytoelements. This set a limit to the scale at which models, based on Beer's law, can account for structural features of vegetation canopies and provide an adequate prediction of the radiation regime. The aim of our paper is to analyze radiation interaction in v...

14 Three-Dimensional Radiative Transfer in Vegetation Canopies

Interaction of photons with a host medium is described by a linear transport equation. This equation has a very simple physical interpretation; it is a mathematical statement of the energy conservation law. In spite of the different physics behind radiation transfer in clouds and vegetation, these media have certain macro and micro-scale features in common. First, both are characterized by stro...

BOSTON UNIVERSITY GRADUATE SCHOOL OF ARTS AND SCIENCES Thesis STOCHASTIC MODELING OF RADIATION REGIME IN DISCONTINUOUS VEGETATION CANOPIES

Acknowledgments First, I wish to thank my advisor, Ranga Myneni, for his truly energetic guidance of my scientific work. His words and actions taught me the importance of labor and persistence, necessary to perform research at a high level and how to participate in large scientific projects. I am also grateful to Yuri Knyazikhin for his superb assistance with nearly every practical aspect of my...

Synergistic algorithm for estimating vegetation canopy leaf area index and fraction of absorbed photosynthetically active radiation from MODIS and MISR data

A synergistic algorithm for producing global leaf area index and fraction of absorbed photosynthetically active radiation fields from canopy reflectance data measured by MODIS (moderate resolution imaging spectroradiometer) and MISR (multiangle imaging spectroradiometer) instruments aboard the EOS-AM 1 platform is described here. The proposed algorithm is based on a three-dimensional formulatio...

Impact of Submerged Aquatic Vegetation on Radiative Transfer and Hyperspectral Remote Sensing in Optically Shallow Waters: Continued Analysis of CoBOP Data

The goals of this study are to develop models of radiative transfer for optically shallow waters with benthic substrates colonized by submerged aquatic vegetation (SAV). The models will enable prediction of upward spectral radiation from the seafloor, thereby permitting (i) the use of optical remote sensing to retrieve bathymetry, (ii) the search for submerged objects of anthropogenic origin an...
