17. EVAPOTRANSPIRAÇÃO DA MELANCIA IRRIGADA POR MEIO DO SEBAL, BALANÇO HÍDRICO E CORRELAÇÕES TURBULENTAS / ESTIMATING IRRIGATED WATERMELON EVAPOTRANSPIRATION USING SEBAL, SOIL-WATER BALANCE AND EDDY CORRELATIONS
In applications of the SEBAL (Surface Energy Balance Algorithm for Land) algorithm parameters for physical processes adjusted for other regions of the planet are commonly used. Therefore, there is a need for validation of the estimates made with the algorithm compared with other conventional methods of estimating evapotranspiration. Thus, this study main goa

19. Uso de imagens ALOS/PALSAR multipolarizadas para detecção de incremento de desflorestamento na Amazônia / Use of multipolarized ALOS/PALSAR image for detection of increment of deforestation in the Amazon
The Amazon forest is a region of rainforest, which has about 5,4 million square kilometers, and with great biodiversity of species on the planet. However, its traditional model of occupation has lead to significant levels of increase of deforestation in the brazilian Legal Amazon. Through remote sensing, these areas can be constantly monitored, offering rate
