Variabilidade local e regional da evapotranspiração estimada pelo algoritmo SEBAL [PDF]

Engenharia Agrícola, 2010
Em face da importância em conhecer a evapotranspiração (ET) para uso racional da água na irrigação no contexto atual de escassez desse recurso, algoritmos de estimativa da ET a nível regional foram desenvolvidos utilizando-se de ferramentas de sensoriamento remoto.

CONSIDERAÇÕES SOBRE A EVAPOTRANSPIRAÇÃO ESTIMADA PELO ALGORÍTIMO SEBAL NO SEMIÁRIDO BRASILEIRO

Revista de Geociências do Nordeste, 2021
O objetivo principal neste trabalho foi avaliar a estimativa da evapotranspiração pelo algoritmo SEBAL (surface energy balance algorithm for land) no semiárido brasileiro. Para isso foi feito um levantamento bibliográfico acerca do tema, para diagnosticar se há convergência sobre a eficiência da utilização do SEBAL na aplicação e planejamento dos ...

Estimation of the Evapotranspiration of Irrigated Açaí (Euterpe oleracea M.), through the Surface Energy Balance Algorithm for Land—SEBAL, in Eastern Amazonia

Water, 2023
The culture of açaí (Euterpe oleraceae M.), originating from floodplain areas, was planted on dry land in many properties in Pará, Brazil, making necessary the use of irrigation. To irrigate adequately with less waste, it is necessary that studies aim at

A MODIS-Based Energy Balance to Estimate Evapotranspiration for Clear-Sky Days in Brazilian Tropical Savannas

Remote Sensing, 2012
Evapotranspiration (ET) plays an important role in global climate dynamics and in primary production of terrestrial ecosystems; it represents the mass and energy transfer from the land to atmosphere.
