Seasonal Climate Patterns and Their Influence on Calibration of the Hargreaves-Samani Equation [PDF]
Hydrological Sciences Journal, 2015 AbstractAnnual patterns in climate parameters were studied to evaluate how these influence the quality of reference evapotranspiration (ETo) estimates obtained from the Hargreaves-Samani (HS) equation, since the method only uses the measured temperature directly. The work evaluates how these patterns can be used to improve the HS ETo estimates.

A Monthly Regression Correction Model for the Hargreaves–Samani Method in Mainland China
Irrigation and Drainage, 2020AbstractReference crop evapotranspiration (ET0) is an important parameter for irrigation engineering. It can be calculated using the Penman–Monteith method (PM), which results in ET0‐PM. This study uses ET0‐PM to determine the availability of a monthly linear regression correction model for the Hargreaves–Samani method (HG). The data were obtained from

AbstractDaily meteorological data of 12 years from 838 stations over China were collected and applied to calibrate the HS model by comparison between the values of ET0 calculated from the original HS and those from the PM model. The calibrated HS model was evaluated by the distribution and values of statistical indices.

Journal of Water Resource and Protection, 2013 Reference evapotranspiration (ETo) is an important parameter used in numerous applications, such as climatological and hydrological studies, as well as for water resources planning and management. There are several methods to estimate ETo, being that the FAO Penman-Monteith (EToPM) method is considered standard.

Abstract Rationalized water use has become increasingly important in recent years, due to deficient rain distribution and increased water demands, such as in forestry and agricultural production. Evapotranspiration is an important variable of the hydrological cycle and one of the main components of the hydrological balance in the soil.

It is suggested by the Food and Agriculture Organization of the United Nations (FAO) to use the FAO56-Penman-Monteith (FAO56-PM) model as the standard model in reference crop water consumption studies. However, the climate parameters required by the standard model cannot be fully and reliably obtained in under developed or developing countries.

Different methods in water saving are applied to maintain the landscapes and reduce the amount of water needed to be irrigated in public parks. Scheduled watering is the most common type of method used by public parks, in which estimating the amount of water leads to over or under irrigation.
