Leaf Area Index Estimation from Visible and Near-Infrared Reflectance Data
نویسندگان
چکیده
A two-stream description of the interaction of radiation with vegetation and soil is tested with experimental data for a corn canopy. The results indicate that the two parameters of the theory (reflectance of a dense canopy and the attenuation coe~cient for radiation in the canopy) can be estimated for the Thematic Mapper spectral bands. A collection of soil reflectance data is used to develop relationships between near-infrared reflectance and visible reflectances. Jointly the canopy and soil formulations verify the potential for estimating leaf area index from radiation measurements in the visible and near-infrared.

Determination of Leaf Relative Water Content of Two Genotypes of Sesame Using Visible and Near- Infrared (VIS/NIR) Spectrometry to Detect Drought Stress
Relative water content (RWC) in plants is one of the most important biochemical parameters and its deficiency limits efficiency of photosynthesis and crop productivity. The scientific reports on using spectroscopy in detecting drought stress for sesame plants are very rare. In this study, the possibility of identifying water stress in two sensitive (Naz-Takshakhe) and resistant (Yekta) genotype...

This study presents a method for quantitatively estimating leaf area index (LAI) in winter wheat by exploring bi-directional reflectance distribution function (BRDF) data. In BRDF data, near-infrared reflectance (NIR) which is sensitive to crown component, canopy cover and crown shape, is affected by illuminated crown component, while red reflectance is sensitive to canopy gaps and controlled b...

متن کاملPhysical and Physiological Basis for the Reflectance of Visible and Near-Infrared Radiation from Vegetation
Knowledge of how solar radiation interacts with vegetation is necessary to interpret and process remote sensing data of agricultural and many natural resources. A plant leaf typically has a low reflectance in the visible spectral region because of strong absorption by chlorophylls, a relatively high reflectance in the near-infrared because of internal leaf scattering and no absorption, and a re...

A two-stream approximation model of radiative transfer is used to calculate values of hemispheric canopy reflectance in the visible and near-infrared wavelength intervals. Simple leaf models of photosynthesis and stomatal resistance are integrated over leat orientation and canopy depth to obtain estimates of canopy photosynthesis and bulk stomatal or canopy resistance. The simple ratio (SR) of ...
