Errors in the estimated constituent concentrations in optically complex waters due solely to sensor noise in a spaceborne hyperspectral sensor can be as high as 80% or more. The goal of this work is to elucidate the effect of signal-to-noise ratio (SNR) on the accuracy of retrieved constituent concentrations. The large variation in the magnitude and spectral shape of the measured signal due to the wide range of constituent concentrations in coastal waters complicate the impact of SNR on the accuracy of estimation. Due to the low reflectance of water, especially in the near infrared region, the actual SNR encountered …
