Abstract

A study was performed to evaluate the bulk aerodynamic method for estimating daytime variation of sensible heat flux (H_A) for a wetted and non-wetted grass canopy under clear and cloudy days. The aerodynamic resistance applied was corrected for atmospheric stability using the Oregon State University One-Dimensional Planetary Boundary Layer model stability function. The performance of the bulk aerodynamic method was tested with indirect measurements of sensible heat flux (H_B) derived from the Bowen ratio energy balance method on 20-min time intervals. Results indicate that there was a good agreement between HB and HA with a coefficient of correlation of 0.93 and slope of the regression line through the origin of 0.96.
