抄録
The proposed adjustable Bowen ratio instrumentation system consists of a BREB instrumentation system, an internal process to evaluate the calculated evapotranspiration rates, and a system controller that configures the instrumentation system for the acquisition of the most appropriate environmental parameters and hence accurate energy fluxes. There is a need to establish a process in which the reliability of calculated evapotranspiration rates is judged.<BR>In order to develop a procedure to judge the reliability of evapotranspiration rates for the said Bowen ratio instrumentation system, the relationship between the location of the arms of sensors and the boundary layer in which the sensors must be located, was investigated. A modified Bowen ratio instrumentation system was used to measure two evapotranspiration (ET) rates, ETs and ET1, evaluated at two different heights : 50 cm and 90 cm, respectively, at the same location. By comparing the two ET rates and processed data, three possible cases of the locations of the boundary layer relative to the arms were clarified. This clarification procedure could be used to appraise ET rates measured at relatively small fields where the fetch requirement might not always be met, and therefore could be employed for the adjustable Bowen ratio instrumentation system.
