Penman-Monteith, FAO-24 reference crop evapotranspiration and class-A pan data in Australia

Agricultural Water Management, 1995
Abstract The Food and Agriculture Organisation (FAO) methods are recognised as the international standard for estimating reference crop evapotranspiration (ETo). The Penman-Monteith method is currently favoured by the FAO over the FAO-24 methods. The FAO also recommends alternative methods which may be used where there are limited data. In this paper,

Analysis of Meteorological Data Time Step Based on FAO Penman-Monteith Equation

2011 Asia-Pacific Power and Energy Engineering Conference, 2011
Daily reference crop evapotranspiration ET ο was calculated by means of the Penman-Monteith method, and the monthly ET ο value was accumulated based on two different time steps of daily and monthly mean meteorological data. The adopted data include meteorological records from Yanzhou (1981-1986)and Heze weather station (1981-1986), Dingtao weather ...

Sensitivity Analysis of FAO-56 Penman-Monteith Method for Different Agro-ecological Regions of India

Environmental Processes, 2015
This paper analyzes the sensitivity of reference evapotranspiration (ETo) to climatic variables for different agro-ecological regions of India: semi-arid (Kovilpatti and Parbhani), humid (Mohanpur), and sub-humid (Ludhiana and Ranichauri). The FAO-56 Penman-Monteith (FAO-56 PM) method is used to estimate ETo, and sensitivity of ETo has been studied in ...

Simplified forms for the standardized FAO-56 Penman–Monteith reference evapotranspiration using limited weather data

Journal of Hydrology, 2013
New simple algebraic expressions equivalent in accuracy to the “standardized” FAO-56 Penman–Monteith daily reference crop evapotranspiration (ET0) computation procedure are derived. The suggested formulas are based on extensions made to a previously developed simple algebraic formula for the Penman evaporation equation.

Estimation of Paddy Rice Crop Coefficients for Penman-Monteith and FAO Modified Penman Method

2006 Portland, Oregon, July 9-12, 2006, 2006
In 1998, Food and Agriculture Organization addressed that FAO Modified Penman method possibly overestimates consumptive use of water comparing to the measured reference crop evapotranspiration (PET) and Penman-Monteith method can be better choice for accurate PET estimation.
