Abstract:
The energy balance of an irrigated cotton field was determined using the Bowen ratio to partition between sensible and latent heat flux density. These data verified estimates of the sensible heat flux density derived from either profiles of wind and temperature at six levels, or from a simplified aerodynamic method using wind and temperature differences between two levels only. The full profile provided good estimates of the sensible heat flux density, but the diurnal course lagged by ∼ 1 h behind the values obtained from the Bowen ratio. The aerodynamic properties of the crop did not appear to be affected by the row structure of the canopy. Results of the simplified method varied with the selection of levels between which the differences were measured. Flux densities determined across some of the layers consistently matched those obtained by the Bowen ratio, but objective criteria for making the proper choice could not be defined. © 1990.
