The most straightforward method preserves the Bowen ratio, i.e., adjusts both the sensible and the latent heat fluxes by the same percentage, based on the 30-min energy balance residual (Twine et al. 2000). At first, this kind of partitioning was chosen in the absence of a better ... paws on pingree crystal lake ilThe Bowen ratio is used to describe the type of heat transfer for a surface that has moisture. Heat transfer can either occur as sensible heat (differences in temperature without evapotranspiration) or latent heat (the energy required during a change of state, without a change in temperature). The Bowen ratio is generally used to calculate heat lost (or gained) in a substance; it is the ratio of energy fluxes from one state to another by sensible heat and latent heating respectively. pawsons fruit and vegWebApr 24, 2024 · The energy balance Bowen ratio (EBBR) system produces 30-minute estimates of the vertical fluxes of sensible and latent heat at the local surface.
