As water scarcity becomes of greater concern in arid and semi-arid regions due to altered
weather patterns, greater and more accurate knowledge regarding evapotranspiration of
crops produced in these areas is of increased significance to better manage limited water
resources. This study aimed at determining the actual evapotranspiration (ETa) and crop
coefficients (Ka) in California date palms. The residual of energy balance method using a
combination of surface renewal and eddy covariance techniques was applied to measure …
