Annual Actual Evapotranspiration Estimation via GIS Models of Three Empirical Methods Employing Remotely Sensed Data for the Peloponnese, Greece, and Comparison with Annual MODIS ET and Pan Evaporation Measurements

ISPRS Int. J. Geo Inf., 2021
Actual evapotranspiration (ETa) has been insufficiently investigated in Greece. This study aimed to estimate annual ETa by empirical methods (Turc, modified Turc, and Coutagne) for the Peloponnese, Greece, a Mediterranean testbed, between 2016–2019, four

Laboratory Comparison of Evaporation Rate Between Colorado Sanken Evaporation Pan and Class A Evaporation Pan (Case Study: Semnan, Iran)

, 2023
One method of estimating the evaporation rate (ER) is to use a variety of evaporation pans, such as the Class A standard evaporation pan (CASEP) and the Colorado Sanken standard evaporation pan (CSSEP). In this study, the rate of evaporation of CASEP and CSSEP have been investigated and compared with each other. This study was conducted in Semnan, Iran.

Simulation of Pan-Evaporation Using Penman and Hamon Equations and Artificial Intelligence Techniques

, 2021
The evaporation losses are very high in warm-arid regions and their accurate evaluation is vital for the sustainable management of water resources. The assessment of such losses involves extremely difficult and original tasks because of the scarcity of ...

A spatial neural fuzzy network for estimating pan evaporation at ungauged sites [PDF]

Hydrology and Earth System Sciences, 2012
Evaporation is an essential reference to the management of water resources. In this study, a hybrid model that integrates a spatial neural fuzzy network with the kringing method is developed to estimate pan evaporation at ungauged sites.

The aerodynamics of pan evaporation

Agricultural and Forest Meteorology, 2012
Abstract In response to worldwide observations reporting a decline in pan evaporation over the last 30–50 years, we developed an instrumented US Class A pan that replicated an operational pan at Canberra Airport in Australia. The aim of the experimental facility was to investigate the physics of pan evaporation under non-steady state conditions.
