Spatial and Temporal Variability of Potential Evaporation across North American Forests

open access: yesHydrology, 2017
Given the widespread ecological implications that would accompany any significant change in evaporative demand of the atmosphere, this study investigated spatial and temporal variation in several accepted expressions of potential evaporation (PE).

Understanding the daily cycle of evapotranspiration: a method to quantify the influence of forcings and feedbacks [PDF]

open access: yes, 2010
A method to analyze the daily cycle of evapotranspiration over land is presented. It quantifies the influence of external forcings, such as radiation and advection, and of internal feedbacks induced by boundary layer, surface layer, and land surface ...

Sensitivity of Penman–Monteith estimates of reference evapotranspiration to errors in input climatic data

open access: yesJournal of Agrometeorology, 2009
The Penman-Monteith (P-M) equation with its new definition of reference crop evapotranspiration (ET0) is recommended by FAO as the standard method of crop water requirement calculation, and also to compare other methods. The ET0 component of the CROPWAT
