M. Sydor et al., REMOTE-SENSING TECHNIQUE FOR DETERMINATION OF THE VOLUME ABSORPTION-COEFFICIENT OF TURBID WATER, Applied optics, 37(21), 1998, pp. 4944-4950
We use remote-sensing reflectance from particulate R-rs, to determine
the volume absorption coefficient a of turbid water in the 400 < lambd
a < 700-nm spectral region. The calculated and measured values of a(la
mbda) show good agreement for 0.5 < a < 10 (m(-1)). To determine R-rs,
from a particulate, we needed to make corrections for remote-sensing
reflectance owing to surface roughness S-rs,. We determined the averag
e spectral distribution of S-rs, from the difference in total remote-s
ensing reflectance measured with and without polarization. The spectra
l shape of S-rs, showed an excellent fit to theoretical formulas for g
lare based on Rayleigh and aerosol scattering from the atmosphere. (C)
