Resumo | Developing precise algorithms to retrieve optical information from inland waters is critical to increase the applicability of remote sensing data for monitoring purposes. Although semi-analytical (SA) algorithms were developed for ocean waters, they have been adapted and applied for inland and coastal waters with relatively success, but for extremely complex waters validation is yet to be achieved. The objective of this study is to assess the potential of SA algorithms applied to Amazon lakes, which are very dynamic, with high variability of CDOM, detritus and phytoplankton concentration. In order to achieve this, in situ optical data was obtained during five missions between 2015 and 2016, with a total of 102 sampling points. Two SA algorithms design for Amazonian lakes were tested: Spectral Optimization Algorithm (SOA); and Quasi-Analytical Algorithm (QAA). Each algorithm was calibrated, using both the original structure and changes proposed for optically complex waters. The algorithms were initially tested for the whole dataset with not satisfactory results. To improve the algorithm performance, the dataset was further divided in dark lakes (9.5 > TSS > 5.2; 6.4 > CDOM(420 nm) > 2.5 m-1) and bright lakes (25.9 > TSS > 6.8; 2.6 > CDOM(420 nm) > 2.1 m-1), based on the Rrs spectrum. Preliminary results, of this ongoing research, showed that total absorption spectra derived from SOA, when compared to in situ measurements, presented a high agreement in the blue region of the spectra (significant at p < 0.05), whereas for the red part of the spectrum a clear correlation couldnt be observed (p > 0.05). For the QAA algorithm, high uncertainty was observed in the estimation of backscattering (in situ from 0.01 to 1.5 m-1 ) during the calibration phase, resulting in error propagation throughout the modeling. Although the authors tested both exponential and logarithmic equations to quantify the backscattering, the results were poor for all the lakes. Therefore, the initial results showed that the SA algorithms designed for Case-1 and Case-2 need to be restructured and validated to be successfully applied to optically complex waters, such those from Amazon floodplain lakes. |
