Agricultural Water Management, 2008
Abstract Estimation of the design water requirement (DWR) is a key part of design and operation of agricultural water resource systems. DWR is determined from frequency analysis of crop water requirement, and the reference return period has been 10 years in South Korea.

Abstract Grass reference evapotranspiration (ETo) is an important agrometeorological parameter for climatological and hydrological studies, as well as for irrigation planning and management. There are several methods to estimate ETo, but their performance in different environments is diverse, since all of them have some empirical background.

Analysis of Meteorological Data Time Step Based on FAO Penman-Monteith Equation
2011 Asia-Pacific Power and Energy Engineering Conference, 2011Daily 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 ...

Estimation of Paddy Rice Crop Coefficients for Penman-Monteith and FAO Modified Penman Method
2006 Portland, Oregon, July 9-12, 2006, 2006In 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.

Impacts of Global Climate Change, 2005
Scientifically based irrigation scheduling programs are valuable tools to assist farmers in improving on-farm water management. Program effectiveness is dependent upon the accurate computation of crop evapotranspiration (ET). The Penman-Monteith equation is widely accepted as the most accurate method to estimate reference crop ET where the climatic ...

Journal of Irrigation and Drainage Engineering, 2007
The climate in Georgia and other southeastern states of the United States is considered to be humid and the annual precipitation is usually greater than the annual potential evapotranspiration (ET). However, during several months of the year, supplemental irrigation is needed to prevent yield reducing water stress due to the temporal rainfall ...

Agricultural and Forest Meteorology, 2007
Real-time irrigation management and water resources allocation need real-time prediction of daily reference evapotranspiration (ETo). Thus, adopting the FAO Penman–Monteith (FAO-PM) equation as the standard for ETo estimation, an attempt was made to predict daily ETo using the public weather forecast messages available in China.

Journal of Agricultural Engineering (India), 2004
The pan evaporation-based model: Christiansen and the combination-based model: Penman Monteith FAO-56 were used to estimate reference evapotranspiration at different locations. Of Assam, India. The locations include meteorological stations at Dibrugarh, Dhubri, Goalpara, Golaghat, Gauhati, Gohpur, Lumding, Margherita, Nagrakata, North Lakhimpur ...

his study focuses on data analysis and assessment of the influence of meteorological parameters on Evapotranspiration (ETo) values calculated by the FAO Penman-Monteith Equation on the daily time interval. This equation is known as a reliable method for estimating ETo due to the study of meteorological parameters such as temperature, humidity, wind ...

The present study used Monte Carlo (MC) simulations to characterize the sensitivity of the FAO-56 Penman–Monteith reference evapotranspiration (ET0) model to the climate variables used in its application. The analysis was performed separately for four climate stations representing different climate regimes of India.
