Comparison of Bowen-Ratio, Eddy-Correlation, and Weighing-LysimeterEvapotranspiration for Two Sparse-Canopy Sites in Eastern Washington

摘要

This report presents results of evapotranspiration (ET) research at two sparse-canopy sites on the ALE Reserve. In this study, the Bowen-ratio method, eddy-correlation method, and lysimeters were used to estimate ET at these two sites. The purposes of this part of the series of ET projects were to (1) compare several methods of estimating ET at two semiarid sites in eastern Washington, (2) investigate reasons for different results from these methods, and (3) estimate long-term (more than 1 year) daily ET for two sites.
