History and Progress of Developing Basal Crop Coefficients for Estimating Crop Evapotranspiration

International Journal of Agronomy, Volume 2025, Issue 1, 2025.
Efficient agricultural water management relies on accurate estimates of crop water use. A key component of this is quantifying evapotranspiration (ET), the combined process of evaporation of water through soil evaporation (E) and plant transpiration (T), which varies with weather, crop type, and management.

Spatial variability of coffee plant water consumption based on the SEBAL algorithm

, 2019
: Awareness of evapotranspiration (ET) and crop coefficient (Kc) is necessary for irrigation management in coffee crops. ET and Kc spatial variabilities are disregarded in traditional methods.

Simplified SEBAL method for estimating vast areal evapotranspiration with MODIS data

Water Science and Engineering, 2011
The SEBAL (surface energy balance algorithm for land) model provides an efficient tool for estimating the spatial distribution of evapotranspiration, and performs a simple adjustment procedure to calculate sensible heat flux using the wind speed data set

Assimilation of Sentinel‐Based Leaf Area Index for Modeling Surface‐Ground Water Interactions in Irrigation Districts

Water Resources Research, Volume 60, Issue 10, October 2024.
Abstract Vegetation‐related processes, such as evapotranspiration (ET), irrigation water withdrawal, and groundwater recharge, are influencing surface water (SW)—groundwater (GW) interaction in irrigation districts. Meanwhile, conventional numerical models of SW‐GW interaction are not developed based on satellite‐based observations of vegetation ...

Improved 30‐m Evapotranspiration Estimates Over 145 Eddy Covariance Sites in the Contiguous United States: The Role of ECOSTRESS, Harmonized Landsat Sentinel‐2 Imagery, Climate Reanalysis, and Deep Neural Network Postprocessing

Water Resources Research, Volume 60, Issue 4, April 2024.
Abstract This study developed and evaluated 30‐m daily evapotranspiration (ET) estimates using the Priestley‐Taylor Jet Propulsion Laboratory (PT‐JPL) model with ECOSTRESS, Moderate MODIS, harmonized Landsat Sentinel‐2 (HLS) imagery, ERA5‐Land reanalysis, and eddy covariance measurements. The new daily 30‐m ET showed significantly improved performance (

Assessing the impact of atmospheric corrections on modeling surface energy balance fluxes with SEBAL [PDF]

, 2008
Thermal and optical remote sensing data with the Surface Energy Balance Algorithm for Land (SEBAL) provide an appropriate basis for modelling energy fluxes at regional scale. This study compares SEBAL applied to ASTER data with in-situ-measurements.

Evaluation of SEBAL model for Evapotranspiration mapping in Iraq using remote sensing and GIS

, 2022
Evapotranspiration is one of the major parameter in the hydrologic cycle. Standard measurements of this parameter is quite complex due to various factors such as variation of precipitation amount, spatial variation by latitude and longitude and changes ...

Land Data Assimilation: Harmonizing Theory and Data in Land Surface Process Studies

Reviews of Geophysics, Volume 62, Issue 1, March 2024.
Abstract Data assimilation plays a dual role in advancing the “scientific” understanding and serving as an “engineering tool” for the Earth system sciences. Land data assimilation (LDA) has evolved into a distinct discipline within geophysics, facilitating the harmonization of theory and data and allowing land models and observations to complement and ...

Radiation balance and urban land use (case study: Kermanshah city) [PDF]

تحقیقات کاربردی علوم جغرافیایی, 2019
Population growth and urbanization development are the main triggering factors of changes in urban land uses. These, in turn, result in changes in the components of radiation balance.
