Journal ArticleDOI
Reference Crop Evapotranspiration from Temperature
TL;DR: In this paper, an equation is presented that estimates ETo from measured values of daily or mean values of maximum and minimum temperature. But this equation is compared with various other methods for estimating ETo.
Journal ArticleDOI
Estimating Potential Evapotranspiration
TL;DR: In this article, four methods for estimating potential evapotranspiration are compared and evaluated: the Class A evaporation pan located in an irrigated pasture area, the Hargreaves equation, the Jensen-Haise eguation, and the Blaney-Criddle method.
Journal ArticleDOI
History and Evaluation of Hargreaves Evapotranspiration Equation
TL;DR: A brief history of development of the 1985 Hargreaves equation and its comparison to evapotranspiration (ET) predicted by the Food and Agricultural Organization of the United Nations (FAO) Penman-Monteith method are described to provide background and information helpful in selecting an appropriate reference ET equation under various data situations as discussed by the authors.
Journal ArticleDOI
Defining and Using Reference Evapotranspiration
TL;DR: In this paper, the Penman combination equation has been used to estimate the reference evapotranspiration (ET) measured by lysimeters of various grasses and/or alfalfas.
Journal ArticleDOI
Irrigation Water Requirements for Senegal River Basin
TL;DR: In this paper, a procedure is recommended for estimating crop water requirements that only requires the measurement of maximum and minimum temperatures, although calibrated for the Senegal River Basin using climatic data from four representative locations appears to be generally applicable for other areas without calibration.
