abstract in recent years, automatic weather stations have been widely used for recording meteorological data in different time scales. therefore the accurate estimation of eto by combination equations can be evaluated using these set of short time scales data. daily eto can also be calculated by summation of hourly eto values. the purpose of this study is to compare the eto values estimated by ...

abstract potential evapotranspiration is one of basic parameter in hydrologic cycle that should be estimate in irrigation design and scheduling, watershed hydrology studies. many applications in diverse disciplines require estimates of evapotranspiration (et) at hourly or smaller time steps. the primary objectives of this study were to compare the american society of civil engineers (asce) and ...

Hourly solar radiation information is necessary to increase the effectiveness of photovoltaic (PV) energy systems. However, compared with daily average radiation, measurement hourly much less available. In this study, a multilayer perceptron artificial neural network based on proposed estimate amount radiation. The method also relies location PV system, hour when needed, and month needed. Two s...

In recent years, more than 50 million advanced (smart) metering infrastructure units have been installed by the U.S electric utilities. Although, smart metering can provide hourly or sub-hourly customer load, it has failed to directly benefit and provide actionable information to consumers and engage them in energy savings. Using nonintrusive load monitoring techniques, the smart metering data ...

abstract evapotranspiration as one of the most important components of the hydrologic cycle, plays a key role in water resources management, crop yield simulation and irrigation scheduling. therefore, presenting a low cost and precision model is very essential for calculations of hourly eto. although, there are empirical formulas, their performances are not all satisfactory due to the complicat...
