Abstract
A study was performed at the Panguilemo Evapotranspiration Investigation Plot (ETIP) located 11 km north of Talca, Chile (35º23´ South and 71º West; 110 m above the sea level) to evaluate latent heat flux by using the Penman-Monteith method.
Data collected on a 20 minute time intervals included latent heat flux (LE), net radiation (Rn), soil heat flux (G), air temperature (Ta), relative humidity (RH), and wind speed (V).
The performance of the Penman-Monteith equation (LEPM) was tested with latent heat flux measurements from the eddy correlation system (LEED) over a grass canopy under different soil moisture conditions.
Results indicate that there was a good agreement between LEPM and LEED with an overall standard error of estimate (SEE) of 45 W.m-2 and an absolute relative error of 6.2 %.
