Quantitative Estimation of Tobacco Copper Ion Content from Hyperspectral Data by Inverting a Modified Radiative Transfer Model: Algorithm and Preliminary Validation

<div>Specific absorption coefficients of water (a), dry matter (b), chlorophyll (c), and copper ion (d). The wavelength of chlorophyll is plotted in the range of 400–800 nm for, at the other wavelength, the specific absorption of chlorophyll is zero.</div>
