Potential evapotranspiration (PET) is crucial for water resources assessment. In this regard, the FAO (Food and Agriculture Organization)–Penman–Monteith method (PM) is commonly recognized as a standard method for PET estimation. However, due to requirement of detailed meteorological data, the application of PM is often constrained in many regions. Under such circumstances, an alternative metho...

The objective was to perform a comparative study of the meteorological elements data that most cause changes in reference Evapotranspiration (ETo, mm) and its own value, automatic weather stations AWS conventional CWS Sertão Agreste regions Pernambuco State. ETo calculated on daily scale using standard method proposed by Food Agriculture Organization (FAO), Penman-Monteith (FAO-56). information...

The absolute prediction of reference evapotranspiration (ETo) is an important issue for global water balance. Present study demonstrated the performance k-Nearest Neighbour (kNN) and Artificial Neural Network (ANN) models daily ETo using four combinations climatic data. kNN ANN were studied climate data during 1996-2015 in Middle Anatolia region. findings estimation with classed FAO Penman Mont...

Journal: :Remote Sensing 2021

This study analysed the uncertainty and sensitivity of core intermediate input variables a remote-sensing-data-based Penman–Monteith (PM-Mu) evapotranspiration (ET) model. We derived absolute relative uncertainties measured meteorological remote-sensing-based atmospheric land surface parameters PM-Mu Uncertainties important data components (i.e., net radiation aerodynamic resistances) were also...
