Reference and Crop Evapotranspiration
2012Advancements have been made in estimating potential and reference evapotranspiration. Actual crop evapotranspiration estimation still is a challenge due to limited availability of local crop coefficients and large-scale variation in field conditions.

Estimating Reference Crop Evapotranspiration with ETgages
Journal of Irrigation and Drainage Engineering, 2009Three years of daily reference evapotranspiration measured by atmometers ( ETg ) were compared to the values computed from the ASCE standardized Penman–Monteith equation ( ETr ) using co-located me...

Crop Genomics Goes Beyond a Single Reference Genome
Trends in Plant Science, 2019The inadequacy of a single reference genome to capture the full landscape of genetic diversity within a species constrains exploration of genetic variation for crop improvement. A recent study by Yang et al. has demonstrated the value of multiple reference-quality genomes in capturing structural variants and guiding biological discovery.

Estimating reference crop evapotranspiration using HGA-LSSVM
2010 Sixth International Conference on Natural Computation, 2010Reference crop evapotranspiration (ETo) is the basis for estimating crop evapotranspiration and for computing crop irrigation requirements. In recent years, Least squares support vector machines (LSSVM) have been applied to forecasting in many areas of engineering. In this paper, a novel hyper-parameter selection for LSSVM regression is presented based

Predicting reference evapotranspiration for screenhouse-grown crops
Agricultural Water Management, 2014Abstract The purpose of the study is to estimate the reference evapotranspiration of screenhouse-grown crops (ET o,in ) from routine outside weather data and main screenhouse characteristics. To this aim, all the microclimatic variables required to calculate ET o,in by means of the standard FAO-56 Penman–Monteith formula were measured under three ...

Trends in reference crop evapotranspiration over Iran
Journal of Hydrology, 2011Summary This study examined the trends in reference crop evapotranspiration (ET0) on monthly and annual time scales in Iran. ET0 was estimated using the globally accepted Food and Agriculture Organization (FAO) Penman Monteith method (FAO-56 PM) over the 16 weather stations located in the different regions of Iran.

Accuracy of Estimated Reference Crop Evapotranspiration
Journal of Irrigation and Drainage Engineering, 1989Evapotranspiration from cool‐season grasses is used as the reference for ET0. The requirements for local calibration for three equations for ET0 recommended by the Food and Agriculture Organization of the United Nations (FAO) are shown for different climatic regions of California.

Agricultural Water Management, 2016
Abstract Despite of the great advancement of technologies for water supply, irrigation management remains inadequate in most areas. The lack of basic information on crop water needs is one of the causes for inadequate water use and irrigation management.

Reference crop evapotranspiration determined with a modified Makkink equation
Hydrological Processes, 1998A modified version of the Makkink equation is shown to be a suitable alternative for Penman's formula for the determination of the crop reference evapotranspiration Eref that is used in the so-called crop factor approach. Makkink's equation requires solar radiation and temperature data only. Since 1987 the Royal Netherlands Meteorological Institute has
