| Abstract | The water represents a complex mixture of a variety of dissolved or particulate materials. These materials have different optical properties that interact with light in different ways in function of their nature and concentration. Quantitative interpretations of the detected signal by remote sensors in terms of water materials require that the effects caused by variations in the incident light field should be also considered. Optical properties of inland water vary spatially and temporally corresponding to changes in the concentration of water materials. Thereupon, the water color modeling aims to express the remote sensing reflectance in terms of Inherent Optical Properties (IOPs), such as total absorption coefficient (at). The development of models for deriving IOPs from Apparent Optical Properties (AOPs) has been essential for achieving determinations of water IOPs. One algorithm used to estimate the (at) is the Quasi-Analytical Algorithm (QAA). The aim of this paper was to apply the QAA in a tropical hydroelectric reservoir, during the dry reason, and evaluate their sensibility in estimate (at) using the remote sensing reflectance (Rrs). The results showed that for shorter wavelengths (443 e 560nm) the absorption was dominated by non-algal particle (aNAP) and for 665 e 700nm the absorption by phytoplankton was dominant (aphy). The QAA tends to underestimate the (at) for wavelengths from 450 to 600nm and superestimate for wavelengths from 650 to 700nm. The highest errors were found at wavelengths 400 and 700nm and the lowest at 600-650nm. We can conclude that QAA starts to lose its potential when the concentration of non-algal particle increases. |
