Sebal Based Evapotranspiration Estimation for Upper Tapi Basin (India)

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Evapotranspiration is one of the important component in hydrological cycle and plays a major role in water balance studies of tropical and subtropical areas. Estimation of actual evapotranspiration using remote sensing is a step towards the real time spatial mapping of evapotranspiration.

Evapotranspiration estimation based on the SEBAL model in the Nansi Lake Wetland of China

Mathematical and Computer Modelling, 2011
As a major component of the water budget of a wetland, evaporation has proven difficult to measure evapotranspiration accurately. This paper developed a scheme to assess actual evapotranspiration (ETa) across a range of land uses in Nansi Lake Wetland, China, using a remote sensing technique and the Surface Energy Balance Algorithm for Land (SEBAL ...

Monin–Obukhov length as a cornerstone of the SEBAL calculations of evapotranspiration

Journal of Hydrology, 2007
Summary The paper looks at the pivotal role that the Monin–Obukhov length (L) can play within the sensible heat balance method for calculating evapotranspiration from remotely sensed multispectral data. It focuses on the possibility of using L as a cornerstone parameter for calculations of sensible heat flux from the pixel data.

Developing surrogate pixels for comparing SEBAL ET with lysimeter ET measurements

IEEE International Geoscience and Remote Sensing Symposium, 2003
SEBAL (Surface Energy Balance Algorithm for Land) is an image-processing model comprised of twenty-five submodels for calculating evapotranspiration (ET) as a residual of the surface energy balance. SEBAL was developed in the Netherlands by Bastiaanssen and has been applied in many developing countries.

Satellite‐based ET estimation in agriculture using SEBAL and METRIC

Hydrological Processes, 2011
AbstractSurface Energy Balance Algorithms for Land (SEBAL) and Mapping EvapoTranspiration at high Resolution with Internalized Calibration (METRIC) are satellite‐based image‐processing models that calculate evapotranspiration (ET) as a residual of a surface energy balance.

Evapotranspiration on the Watershed Scale Using the SEBAL Model and Landsat Images

2001 Sacramento, CA July 29-August 1,2001, 2001
SEBAL (Surface Energy Balance Algorithm for Land) is an image-processing model comprised of twenty-five submodels that calculates evapotranspiration (ET) and other energy exchanges at the earth’s surface. SEBAL uses image data from Landsat or other satellites measuring thermal infrared radiation, visible and near-infrared. SEBAL was developed in the

Energy balance from images in humid climate – SEBAL and METRIC

Agrometeoros, 2018
Evapotranspiration is an important phenomenon to agriculture; therefore, this work aims at verifying the suitability of the SEBAL and METRIC models to estimate latent heat flux using remote sensing data from grain cultivation areas in the northwestern subtropical region of Rio Grande do Sul. This region stands out for grain production.

Assessment of SEBAL model for estimating evapotranspiration in the Devils Lake basin

2006 Portland, Oregon, July 9-12, 2006, 2006
Above-average rainfall in the last twelve years has led to rising water levels in the Devils Lake basin in northeastern North Dakota. An irrigation test project has been started at ten farmercooperator field sites within the basin to estimate how much additional water can be utilized via irrigation of agricultural crops.

Adaptation of SEBAL for estimating groundnuts evapotranspiration, in Cyprus

South-Eastern European Journal of Earth Observation and Geomatics, 2012
The imperative need for data on irrigation management in Cyprushas led to a turnoff regarding the method of collecting and analyzing irrigation management primary data. The time and money consuming direct measurements of evapotranspiration (ETc), such as Pan-evaporation methods, lysimeters and others, are substituted from efficient energy and ...

Sensitivity Analysis of the Surface Energy Balance Algorithm for Land (SEBAL)

Transactions of the ASABE, 2009
New versions of evapotranspiration (ET) algorithms based on the Surface Energy Balance Algorithm for Land (SEBAL) are being published, each containing slightly different equations to calculate the energy balance. It is difficult to determine what impact changing one or more of the equations or coefficients in the series of equations of SEBAL has on the
