Determining fPAR and leaf area index of several land cover classes in the Pot River and Tsitsa River catchments of the Eastern Cape, South Africa [PDF]

open access: yes, 2017
Determining the quantum (both annual maxima and minima) and the temporal variation in the leaf area index (LAI), and the fraction of photosynthetically active radiation (fPAR), are three fundamental biophysical characteristics of the plant canopy that ...

Seasonal Evapotranspiration Patterns in Mangrove Forests [PDF]

open access: yes, 2014
Diurnal and seasonal controls on water vapor fluxes were investigated in a subtropical mangrove forest in Everglades National Park, Florida. Energy partitioning between sensible and latent heat fluxes was highly variable during the 2004–2005 study period.

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).

Comparison of different methods in estimating potential évapotranspiration at muda irrigation scheme of Malaysia [PDF]

open access: yes, 2012
Evapotranspiration (ET) is a complex process in the hydrological cycle that influences the quantity of runoff and thus the irrigation water requirements. Numerous methods have been developed to estimate potential evapotranspiration (PET).

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
