Abstract:
The results of a study aimed at the determination of the concentration
of Rhodamine-B dye at parts per billion (ppb) levels from remotely-sensed
optical reflectancespectra of marine and fresh water are described. An estimated
signal is derived from spectral radiometer data using an improved cross correla-
tion technique. In applying this technique use is made of the fact that some
a priori information is available regarding the spectral distribution of the signal
produced by the dye. The procedure for calibrating the signal estimate with
ground truth data is described.
