Regional estimation of daily to annual regional evapotranspiration with MODIS data in the Yellow River Delta wetland [PDF]

, 2009
Evapotranspiration (ET) from the wetland of the Yellow River Delta (YRD) is one of the important components in the water cycle, which represents the water consumption by the plants and evaporation from the water and the non-vegetated surfaces.

Climate variability impact on crop evapotranspiration in the upper East region of Ghana

Environmental Challenges
Ghana's agriculture is primarily rain-fed, making it vulnerable to the impact of climate variability and climate change. This study examined the trends and impact of climatic variability and evapotranspiration on the crop evapotranspiration of selected ...

Water requirement and crop coefficients of sorghum in Apodi Plateau

Revista Brasileira de Engenharia Agrícola e Ambiental, 2021
Sorghum is of significant economic importance for Northeastern Brazil, since it exhibits high growth rates in regions with irregular rainfall distribution and high temperatures, and is an alternative to corn, which has greater water requirements. Despite

Assessing Crop Coefficients for Natural Vegetated Areas Using Satellite Data and Eddy Covariance Stations

Sensors, 2017
The Food and Agricultural Organization (FAO) method for potential evapotranspiration assessment is based on the crop coefficient, which allows one to relate the reference evapotranspiration of well irrigated grass to the potential evapotranspiration of ...

New Evapotranspiration Crop Coefficients [PDF]

Journal of the Irrigation and Drainage Division, 1982
Improved crop coefficients for various Pacific Northwest irrigated crops were developed for estimating crop evapotranspiration (ET) from estimates or measurements of reference ET. Reference ET was based on that for well watered, actively growing alfalfa with sufficient growth for near maximum ET in arid, irrigated regions.

Crop Simulation and Crop Evapotranspiration for Irrigation Management of Spinach [PDF]

HortScience, 2006
Improving irrigation water management for crop production is becoming increasingly important in South Texas as the water supplies shrink and competition with urban centers in the region grows. Crop simulators and crop evapotranspiration (ET) are appealing methods for estimating crop water use and irrigation requirements because of ...

Tomato and cowpea crop evapotranspiration in an unheated greenhouse

Water Science and Engineering, 2008
With the development of protected cultivation of vegetables in China, it is necessary to study the water requirements of crops in greenhouses. Lysimeter experiments were carried out to investigate tomato (2001) and cowpea (2004) crop evapotranspiration ...

Modifying the Dual Crop Coefficients with Leaf Area Index and Meteorological Factors to Improve the Estimated Evapotranspiration from Maize Fields

Guan'gai paishui xuebao, 2023
【Objective】 Evapotranspiration consists of plant transpiration (Tr) and soil surface evaporation (Es); It is a critical component in the hydrological cycle, often estimated using meteorological and plant data.
