Description 762-769
Backscattering
of coastal waters of Arabian Sea off Veraval, Gujarat, India
has been reported using Quasi Analytical Algorithm (QAA) inversion method. The
same is compared with the in-situ
measurements. Present study compares the backscattering coefficient retrieved
from QAA with the measured values of backscattering at 470 and 700 nm. Retrieved
backscattering coefficient using QAA lies between 0.0005-0.0047 m-1 at
470 nm and 0.00006-0.0040 m-1 at 700 nm. This is compared
with the measured backscattering coefficients. Root mean square error (RMSE)
has been computed, taking logarithm (to base 10) of the measured and modeled
values. RMSE for 470 nm is 0.21 and for 700 nm is 0.23. Mean percentage error
has also been computed which is 19.19% at 470 nm and 43.90% at 700 nm. Field
measurements show that the QAA approach overestimates the backscattering
coefficient at 470 nm and 700 nm (19.19% and 43.90% respectively) in the
coastal waters of Gujarat. This is possibly
due to the wavelength model used in the computation of backscattering at
various wavelengths.
