Abstract

The water quality monitoring from space, in Brazil, still a challenge mainly because the integrated studies are non-existent, in different types of inland waters. The majority of studies conducted in Brazil are fragmented, with little interaction between researchers that works in the same theme. Owing that a lot of algorithms are developed, isolated, which often can't be applied directly in different aquatic systems in which the algorithms were calibrated. This occurs mainly because those algorithms have an empirical base, which are locally limited. To overcome these limitations we propose in this project the development of a semi-analytical scheme, which will be based on the Quasi-Analytical Algorithm (QAA); in order to have lower errors the QAA will be re-parameterized using in situ data from our studied reservoirs. This scheme should allow us to estimate the water quality parameters from space, improving the water resources management and monitoring using satellite images. (AU)
