Hi,
I want to compute Floating Algae Index (FAI) and therefore need to claculate the Rayleigh corrected reflectance (Rrc) for Landsat-8 bands (e.g. NIR band 5) in MATLAB.
I have already obtained the TOARef (sun angle corrected Top of Atmosprehre Reflectance) in MATLAB by using functiOn from the following link:
https://www.mathworks.com/matlabcentral/fileexchange/50636-landsat8-radiance-reflectance-brightness-temperature-and-atmospheric-correction
Thus, now I need to obtain the Rayleigh reflectance in MATLAB. Could anyone please help me?
