Scaling PRI Between Coniferous Canopy Structures [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2013 We measured simultaneously the spectral albedo of ten Scots pine shoots and the needles constituting the shoots. Next, we used the spectral information to calculate the photochemical reflectance index (PRI) which allows to retrieve photosynthetic productivity from imaging spectroscopy data.

Principal component analysis of steers performance and structural and nutritional characteristics of Mombasa grass [PDF]
Ciência Rural, 2020 : There is little information about whether the increased secondary productivity observed in pastures fertilized with high nitrogen rates is attributable to fluctuations in the nutritional value or pasture structural characteristics, or both.

Laser scanning reveals bryophyte canopy structure [PDF]
New Phytologist, 2005 We evaluated laser scanning as a method to provide depth measurements for bryophyte canopies at fine spatial scales to derive surface roughness (Lr), a structural parameter. Depths to the first vertical canopy contact were measured on 5 x 5 cm2 areas of 27 bryophyte canopies using a contact probe, a commercial laser scanner and a scanner employing a ...

A Column Canopy‐Air Turbulent Diffusion Method for Different Canopy Structures [PDF]
Journal of Geophysical Research: Atmospheres, 2019 AbstractAn accurate simulation of the sensible heat flux (H) over vegetation from thermal remote sensing requires an a priori estimate of roughness length and the excess resistance parameter kB−1. Despite being the subject of considerable interest in hydrometeorology, there still does not exist a uniform method for estimating roughness length from ...

Characterization of Canopy Layering in Forested Ecosystems Using Full Waveform Lidar
Remote Sensing, 2013 Canopy structure, the vertical distribution of canopy material, is an important element of forest ecosystem dynamics and habitat preference. Although vertical stratification, or “canopy layering,” is a basic characterization of canopy structure for ...

Ciência Rural, 2021 : The animal performance on pasture is directly correlated to canopy structure since this influences the herbage consumption. This study was evaluated the effects of four pre-grazing canopy heights (12, 20, 28 and 36 cm) of Andropogon lateralis Ness on ...
