Bowen ratio definition
WebThe Bowen ratio obtained using equation 3.1 to equation 3.8 was combined with the available energy (R N-G) to obtain the sensible and latent heat fluxes using equation 3.7 and equation 3.8, respectively (Figures 2 and 3). It was observed that during the late night and early morning hours, estimated heat fluxes by BR were fairly constant (00.00 ... WebFigure 4.2. 1: Normal L. Bowen.
