Abstract

Remote sensing reflectances measured underwater and above- water in the Gulf of California are compared to evaluate the equivalence between methods. Each form of reflectance is also compared to concurrently measured ratios of scattering to absorption, and the mean backscattering fraction is estimated. Above-water and in-water remote sensing reflectance estimates differ by more than 20 percent, with absolute RMS difference ranging from 0.001 to 0.005. Standard deviations of estimated backscattering fractions are between 15 percent nd 20 percent of the mean at each wavelength.
