Estimation of leaf area index and its sunlit portion from DSCOVR EPIC data: theoretical basis [PDF]
, 2017 This paper presents the theoretical basis of the algorithm designed for the generation of leaf area index and diurnal course of its sunlit portion from NASA's Earth Polychromatic Imaging Camera (EPIC) onboard NOAA's Deep Space Climate Observatory (DSCOVR)

The dependence of canopy layer turbulence on within-canopy thermal stratification [PDF]
Agricultural and Forest Meteorology, 1992 Transport properties near the Earth's surface are strongly influenced by the thermal stratification of the atmosphere. Until now, no distinction has been made between thermal stability parameters within and above a plant canopy, and it has been usual to classify canopy transport processes in terms of above-canopy stability parameters only. The question

Potato crop growth as affected by nitrogen and plant density [PDF]
Pesquisa Agropecuária Brasileira, 2000 Growth and development variables and dry matter characteristics were studied for cultivar Snowden of potato (Solanum tuberosum L.) to evaluate nitrogen and plant density influence. Disregarding ending of season plant stress, the average number of actives

Vertical stratification of selected Hymenoptera in a remnant forest of the Po Plain (Italy, Lombardy) (Hymenoptera: Ampulicidae, Crabronidae, Sphecidae) [PDF]
, 2017 Communities of the canopy of temperate forests are still relatively unexplored. Furthermore, very little is known on how vertical stratification for some insect groups is related to biological strategies.

Relighting Photographs of Tree Canopies [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2011 We present an image-based approach to relighting photographs of tree canopies. Our goal is to minimize capture overhead; thus the only input required is a set of photographs of the tree taken at a single time of day, while allowing relighting at any other time. We first analyze lighting in a tree canopy both theoretically and using simulations.

Nitrogen cycling, forest canopy reflectance, and emergent properties of ecosystems [PDF]
, 2013 In Ollinger et al. (1), we reported that mass-based concentrations of nitrogen in forest canopies (%N) are positively associated with whole-canopy photosynthetic capacity and canopy shortwave albedo in temperate and boreal forests, the latter result ...

Insects, 2017 Fire is one of the most relevant ecological disturbances in nature. Little is known about the effects of fire on biodiversity in ecosystems like rupestrian grasslands, which share characteristics with savanna and forest biomes.

Physical interpretation of the correlation between multi-angle spectral data and canopy height [PDF]
, 2007 Recent empirical studies have shown that multi-angle spectral data can be useful for predicting canopy height, but the physical reason for this correlation was not understood.

Adjustment of a turbulent boundary layer to a 'canopy' of roughness elements [PDF]
, 2003 A model is developed for the adjustment of the spatially averaged time-mean flow of a deep turbulent boundary layer over small roughness elements to a canopy of larger three-dimensional roughness elements.
