Abstract

The Bowen ratio energy balance method has been widely used by many researchers to estimate the fluxes of water vapor and sensible heat between crops and atmosphere. The energy balance for the crop canopy can be expressed as Rn + G + H + LE + PS + M = 0 (1) where Rn is net radiation, G is soil surface heat flux, H is sensible heat flux and LE is latent heat flux.
