The Uncertainty of Penman‐Monteith Method and the Energy Balance Closure Problem
Journal of Geophysical Research: Atmospheres, 2018The Penman‐Monteith (PM) method is considered the most accurate method for estimating reference crop evapotranspiration (ET0). However, the method has obvious flaws in energy balance closure. In this study, the changing trends between latent heat flux of

Abstract Continued development of networks of electronic weather stations worldwide has increased the availability of weather data for calculating ETo on an hourly basis. There has been question and debate as well as studies on the appropriate expression and parameterization for the surface resistance (rs) parameter of the Penman-Monteith (PM ...

Comparing Net Radiation Estimation Methods: CIMIS versus Penman–Monteith
Journal of Irrigation and Drainage Engineering, 2007Net radiation ( Rn ) estimated using the California Irrigation Management Information System (CIMIS) Penman and the Penman–Monteith (PM) methods are compared using hourly data from July 17, 2004 to October 24, 2004. Results showed that differences between the two estimates get larger towards higher values of Rn because of the inability of the two ...

Calculating the Palmer Drought Severity Index (PDSI) using the Thornthwaite potential evapotranspiration (PET) method has come under recent scrutiny for overestimating drought conditions when air temperatures exceed the historical baseline. With increasing air temperatures around the world, calculating the PDSI using the Thornthwaite PET method may no ...

Evapotranspiration (ET) constitutes the dominant water loss from many different types of wetlands. The relative importance of ET is apparent in its influence over water depth, temperature and salinity. However, direct measurement of ET, especially for wetland, is difficult, costly, and rarely available.

The study compares the prediction performances of evapotranspiration by the FAO56 Penman–Monteith method and the pan evaporation method using the artificial neural network. A backpropagation neural network was adopted to determine the relationship between meteorological factors and evapotranspiration or evaporation.

This paper presents the application of a simple procedure for estimating long-term average daily reference evapotranspiration (ETo) in Puerto Rico. With only two parameters, site latitude and surface elevation, it is possible to estimate all other input to the Penman-Monteith method.
