Calculating Daily Reference Evapotranspiration in Erhai Irrigated District with the Evaporation Paradox in Consideration

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Evapotranspiration (ET) is an important process in the hydrological cycle and has been increasing, as shown by both field measurements and satellite remote sensing, at 0.63 mm/year over the past 30 years due to the increased leaf area index ...

Class A pan coefficients (Kp) to estimate daily reference evapotranspiration (ETo) Coeficientes do tanque Classe A (Kp) para a estimativa diária da evapotranspiração de referência (ETo)

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2003
The class A pan coefficient (Kp) has been used to convert pan evaporation (ECA) to grass-reference evapotranspiration (ETo), an important component in water management of irrigated crops. There are several methods to determine Kp values, using wind speed,

Insight into the highly-selective separation of Fe(III) with cinnamon-like blended fiber

open access: yesJournal of Hazardous Materials Letters, 2023
The separation and recovery of Fe(III) in heavy metal mixtures is a great challenge due to its strong ion exchange property. In this study, we developed a novel cinnamon-like blended fiber (PAN/PEG) using electrostatic spinning and dissolution post ...

Class A pan coefficients (Kp) to estimate daily reference evapotranspiration (ETo) [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2003
The class A pan coefficient (Kp) has been used to convert pan evaporation (ECA) to grass-reference evapotranspiration (ETo), an important component in water management of irrigated crops. There are several methods to determine Kp values, using wind speed, relative humidity and fetch length and conditions.
