Estimating daily net radiation in the FAO Penman–Monteith method [PDF]

Theoretical and Applied Climatology, 2016
In this work, we evaluate the procedures of the Manual No. 56 of the FAO (United Nations Food and Agriculture Organization) for predicting daily net radiation using measures collected in Tandil (Argentina) between March 2007 and June 2010. In addition, a new methodology is proposed for estimating daily net radiation over the reference crop considered ...

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

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

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,

Water deficit and water surplus maps for Brazil, based on FAO Penman-Monteith potential evapotranspiration

Ambiente e Agua - An Interdisciplinary Journal of Applied Science, 2008
The climatological water balance (CWB) proposed by Thornthwaite and Mather (1957) is a useful tool for agricultural planning. This method requires the soil water holding capacity (SWHC), rainfall (R) and potential evapotranspiration (PET) data as input.

REFERENCE EVAPOTRANSPIRATION BY PENMAN–MONTEITH FAO 56 WITH MISSING DATA OF GLOBAL RADIATION

Revista Brasileira de Engenharia de Biossistemas, 2016
The aim of this study was to evaluate the errors generated on the reference evapotranspiration (ET0) estimation by Penman-Monteith FAO 56 (PMF 56) when employed simplified models to estimate the global radiation (HG) are based on the air temperature. We evaluated 28 automatic weather stations (EMA's) belonging to the National Institute of Meteorology ...

Irrigation Scheduling and Fertigation of Pole Tomatoes by Using FAO-56 Penman-Monteith Method

, 2013
Fertigation consists of application of irrigation water with plant nutrients to plants. Therefore, both application time and doses of plant nutrients and application time of irrigation and application amounts of water are highly important. Excess watering caused yield reduction because of leaching of plant nutrients below rooting depth and reverse ...
