WebDespite the recent progress, the method has still remained relatively expansive and alternative indirect techniques like Bowen ratio energy balance (BREB), surface renewal analysis, temperature variance or aerodynamic method are used by researchers, mainly if only the latent (LE) and sensible heat (H) fluxes are the primary interest. The presented WebJan 1, 2024 · A number of methods provide reliable point measurements of λE, e.g., the eddy covariance ( EC) and the energy balance Bowen ratio ( BR) tower systems (see Section 19.4 ). Satellite remote sensing does not provide direct measurement of λE.

WebThe Bowen's Ratio is defined as the ratio of sensible to latent heat fluxes at the surface obtained based on thermodynamic considerations and is represented as β = Ha/ (ρWater*L*EL) or Bowen’s Ratio = Sensible heat transfer from water body/ (Water Density*Latent Heat of Evaporation*Daily Lake Evaporation).
