Retrieved actual ET using SEBS model from Landsat-5 TM data for irrigation area of Australia

摘要: Abstract The idea of ground-based evapotranspiration (ET) is the most interesting for land–atmosphere interactions, such as water-saving irrigation, performance irrigation systems, crop water deficit, drought mitigation strategies and accurate initialization climate prediction models especially in arid semiarid catchments where shortage a critical problem. recent year's Australia concerns about change has prominent need to manage resources more sustainably Murrumbidgee catchment which utilizes bulk food security production. This paper discusses application Surface Energy Balance System (SEBS) model based on Landsat-5 TM data field observations been used tested deriving ET over Coleambally Irrigation Area (CIA), located southwest NSW, Australia. 16 scenes were selected covering time period 2009, 2010 2011 estimating actual CIA. To do validation methodology, ground-measured was compared retrieved results derived value CIA much closer measurement. From remote sensing observations, root mean square error (RMSE) 0.74 APD 7.5%. satellite values belong reasonable range.
