{ %%%%%% Algorithm name %%%%%%
biophys\_indices (MCARI is one index calculated within the overall program)
}
%
{ %%%%%% Algorithm summary %%%%%%
Calculation of Modified Chlorophyll absorption in Reflectance Index (MCARI)
}
%
{ %%%%%% Category %%%%%%
Biophysics - narrow band chlorophyll indices
}
%
{ %%%%%% Inputs %%%%%%
Narrow band multi- or hyperspectral imagery (ENVI standard image data) including channels close to the wavelengths of 550nm, 670nm and 701nm.\bigskip
}
%
{ %%%%%% Outputs %%%%%%
Single band with MCARI values
}
%
{ %%%%%% Formula %%%%%%
\begin{displaymath}
MCARI = ((R_{701}-R_{670})-0.2*(R_{701}-R_{550}))*\frac{R_{701}}{R_{670}}
\end{displaymath}
