A novel spectral index for estimation of relative chlorophyll content of sugar beet

Computers and Electronics in Agriculture, 2021
Abstract Fast and non-destructive estimation of canopy chlorophyll content from hyperspectral sensing is essential to monitor the physiological status of vegetation or to estimate crop above ground nitrogen status. The objective of this study is to propose an optimal method for the relative chlorophyll content (SPAD) estimation of sugar beet canopy ...

Normalized difference chlorophyll index: A novel model for remote estimation of chlorophyll-a concentration in turbid productive waters

Remote Sensing of Environment, 2012
Abstract We propose a normalized difference chlorophyll index (NDCI) to predict chlorophyll-a (chl- a ) concentration from remote sensing data in estuarine and coastal turbid productive (case 2) waters. NDCI calibration and validation results derived from simulated and MEdium Resolution Imaging Spectrometer (MERIS) datasets show its potential ...

A modified chlorophyll absorption continuum index for chlorophyll estimation

Journal of Zhejiang University-SCIENCE A, 2006
There is increasing interest in using hyperspectral data for quantitative characterization of vegetation in spatial and temporal scopes. Many spectral indices are being developed to improve vegetation sensitivity by minimizing the background influence.

The MERIS terrestrial chlorophyll index

International Journal of Remote Sensing, 2004
The long wavelength edge of the major chlorophyll absorption feature in the spectrum of a vegetation canopy moves to longer wavelengths with an increase in chlorophyll content. The position of this red-edge has been used successfully to estimate, by remote sensing, the chlorophyll content of vegetation canopies.

Multi-Reservoir System Optimization using Chlorophyll-a Trophic Indexes

Water Resources Management, 2006
The problem of managing water scarcity by resorting to complex interconnected multi-source water systems needs to utilize management optimization techniques analyzing aspects of water quantity and quality in a common strategy. In the southern regions of Mediterranean Europe, the greater part of water resources for supply systems are derived from ...
