The Penman-Monteith equation

2023
The Penman-Monteith is an elegant, physical expression of the process that water vapor follows when transported from inside the leaf of a plant into the atmospheric boundary layer above. The original Penman combination equation (1948) combined the energy input of radiation from the sun and atmosphere with convective transport of temperature and ...

Using the Penman-Monteith Equation Predictively

Agricultural Water Management, 1984
Abstract We consider the problem of calculating evaporation from vegetation which is sited away from a meteorological measurement station, or which is merely proposed. To use the Penman-Monteith equation for this task we must be able to predict, inter alia, the saturation deficit above the new vegetation A strategy for making such prediction is ...

A discussion on and alternative to the Penman–Monteith equation

Agricultural Water Management, 2009
Abstract The Penman–Monteith (PMe) equation that estimates evaporation from leaf/canopy surfaces is based on a few approximations. Several authors discussed ensuing errors and suggested improvements. This paper reminds those discussions which ended in the early nineties.

Accuracy of the Penman-Monteith Equation adjusted for atmospheric stability

Agricultural and Forest Meteorology, 1987
Abstract The influence of atmospheric stability upon the Penman-Monteith equation when estimating maximum evapotranspiration from a whole wheat crop was investigated. A stability function based upon the Richardson number was used. It was measured over a short green grass surface and over the wheat crop.

Non-dimensionalisation of the Penman-Monteith model

Journal of Hydrology, 1995
Abstract The Penman-Monteith model is expressed in non-dimensional form. Scalings are selected such that the groups of dimensionless variables lie between minus one and plus one. The relative importance of each term in the equation is assessed from the size of the dimensionless parameters.

Performance of Penman-Monteith FAO56 in a Semiarid Highland Environment

Journal of Irrigation and Drainage Engineering, 2010
Reliable estimates of evapotranspiration are essential for irrigation and water resources planning and management. Although several methods are available for computing reference evapotranspiration ( ETo ) , the provision of complete and accurate climate data is often a problem.

Atmospheric Stability Effects on Penman-Monteith Evapotranspiration Estimates

Pure and Applied Geophysics, 2005
This study explores surface-layer stability effects on the Penman-Monteith (P-M) method, one of the most widely used methods to estimate evapotranspiration (ET). Stability correction is applied to the original (neutral stability) formula by using atmospheric exchange coefficients developed by Louiset al. (1981). First, the effects of stability on the P-
