Bowen ratio
Webthe energy balance on an evaporation pan is improved to account for sensible heat using the Bowen ratio WebJan 1, 2005 · One of the most widely used methods to determine the evaporative flux from the earth surface is the Bowen Ratio Energy Balance method (BREB). The BREB requires sensors to determine net radiation, soil heat flux density at the soil surface, and gradients of air temperature and vapor pressure. These variables are relatively easy to measure.
