Prediction of soil evaporation measured with weighable lysimeters using the FAO Penman–Monteith method in combination with Richards’ equation [PDF]

Vadose Zone Journal, 2021
Abstract Multiannual data (2016–2018) from 12 weighed lysimeters (four soil types with textures ranging from sandy loam to silt loam, three replicates) of the TERENO SOILCan network were used to evaluate if evaporation ( E ) rates could be predicted from weather data using ...

SENSITIVITY ANALYSIS OF A FAO PENMAN MONTEITH FOR POTENTIAL EVAPOTRANSPIRATION TO CLIMATE CHANGE

Jurnal Teknologi, 2017
Sensitivity of the FAO Penman-Monteith (FPM) potential evapotranspiration (PET) model under tropical climates has been studied in the present study. A total of 17 meteorological stations covering Peninsular Malaysia starting from 1987-2003 were used as model inputs. A sensitivity analysis (SA) was carried out using the graphical method for temperature,

Crop coefficients, growth rates and quality of cool-season turfgrasses [PDF]

, 2015
Determination of crop coefficients (Kc), the ratio between actual (ETa) and reference evapotranspiration (ET0), is necessary to schedule irrigation. Our objective was to determine Kc, turf quality and growth rate under daily irrigation to field capacity (

Evaluation of FAO-56 Penman-Monteith Model Using Alternative Climatic Data Application to Afghanistan [PDF]

Revista Brasileira de Meteorologia, 2019
Abstract The Penman-Monteith model with alternative and measured data in three regions of Afghanistan (Central-North- East) was discussed by estimating reference evapotranspiration (ET0). The result showed that in the high rate of ET0, the difference between ET0 that estimated using alternative and measured data could be more than 2 mm day-1 when using
