[ET.sub.c] has been estimated or measured using other methods, for example, weighing lysimeters, evaporation pan, soil water balance,
atmometer, Bowen Ratio Energy Balance System (BREBS), and Eddy Covariance (EC).
Direct methods include weighing lysimeters and soil water balance estimations, while indirect methods include pan evaporation,
atmometer, Bowen Ratio Energy Balance System (BREBS), Eddy Covariance (EC), scintillometer, sap flow, and remote sensing [1].
Motivated observers were encouraged to purchase a fairly inexpensive
atmometer (~$220) known as an ETgage (Gavilan and Castillo-Llanque 2009) to deploy during the growing season months (Fig.
Behind the last pump in a series, for the purpose of regulation and control of the process, a slurry flowmeters, slurry densitometer,
atmometer in pipeline are to be installed.
At high elevation on Maui, the calculated [P.sub.p] was high (and was consistent with measured
atmometer evaporation rates [E.sub.m]), whereas rainfall was moderate to low.
Potential ET, as monitored with an
atmometer positioned at canopy height, was fairly constant at 3.5 cm [wk.sup.-1].
There are several methods for in situ measurement of ET including pan evaporation (large/small),
atmometers, evapotranspirometers tanks, lysimeters, Bowen ratio [13] based on meteorological data, the eddy covariance method using flux tower measurements, and scintillometers [14].
