Análise Do Desempenho De Modelos De Albedo Da Superfície Em Áreas De Cana-De-Açúcar Com Dados Do Sensor Modis/Terra

Abstract: A cana-de-açúcar é uma cultura de grande importância no Brasil, com uma intensa expansão na região Centro-Sul na última década, principalmente devido à crescente demanda de etanol a partir de 2003. Esse cenário exige que se avaliem os impactos gerados pela expansão da cultura no balanço de radiação e nos fluxos de energia na superfície, que estão intrinsecamente relacionados com os parâmetros de superfície como o albedo. O albedo de superfície é uma das variáveis críticas na modelagem do balanço de radiação, v… Show more

“…For the beginning of the cycle, plants in the beginning of re-growth with straw covered soil, this value was higher (22%). Similar results were found by Oliveira et al (2015) and Moraes and Oliveira (2019), who found a variation of 13 to 20% of the surface albedo, in the phases of full development and initial phase respectively, using MODIS Sensor (250x250 m). For the temperature of vegetated surface, no oscillations were observed in the normal distribution for Landsat 8, due to the spatial resolution being smaller than Sentinel 2, which in turn presents higher oscillation, demonstrated both by the temporal variation of the means and the amplitude of the distribution by date (Figure 1 c, d).…”
