• 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 …

  Algorithms development to retrieve water quality parameters from space, AP.R
• International Geoscience and Remote Sensing Symposium, AR.EXT

• Abstract

  Total suspended matter (TSM) is an important indicator of water quality and has an adverse effect on light propagation in the water affecting the primary production. Moderate Resolution Imaging Spectroradiometer (MODIS) data have been widely used to develop numerous semi-empirical models all over the world. In this study, many of these models perform satisfactorily either in a single wate…

  Retrieving Total Suspended Matter in Tropical Reservoirs within a Cascade System with Widely Differing Optical Properties, PUB.ART

(Only some records are available in English at this moment)

• Abstract

  Reservoirs are artificial aquatic ecosystems that modify the hydrodynamics of rivers. The increased retention time and, consequently, elevation of the nutrients availability time lead to eutrophication of the environment and blooms of algae (phytoplankton). Some species of phytoplankton may produce toxic metabolites for animals and humans. Therefore, the monitoring of water bodies has env…

  Developing a hybrid algorithm to estimate the chlorophyll-a concentration from space, BP.IC

• Abstract

  Understanding the optical water quality in reservoirs designed in a cascade system is of great importance for water resources management, since it is intrinsically related with environmental forcings, land use and land cover and biogeochemical composition of water column constituents. Overall, in a cascade system, the upstream reservoirs are more eutrophic than those further downstream as…
